Identification, Evaluation, and Correction of Supracrestal Tissue Attachment (Previously Biologic Width) Violation: A Case Presentation With Literature Review.

The supracrestal tissue attachment (SCTA) is the new terminology for biologic width. SCTA is defined as the physiologic dimension of a solitary functional unit composed of junctional epithelium and connective tissue attachment. Its preservation is critical for the well-being of periodontal health. SCTA has been widely studied and scientific literature is indicative of its significance during the placement of restoration, including prosthetic crowns. This should be taken care of in cases of anterior teeth within the smile zone, where dental crowns are regularly placed subgingivally for aesthetic reasons. In addition, any violation of SCTA while restoring the dentition will present as gingival inflammation and pain, consequently, leading to failure of the clinical procedure.

Prospective observational cohort study of the change of the marginal bone crest in relation to the prosthetic abutment height and the peri-implant vertical mucosal thickness at implants positioned subcrestally.

AIM: To evaluate the influence on peri-implant crestal bone loss exerted by the vertical mucosal thickness and the abutment height over 12 months after placement of the restoration on subcrestal implants with change of platform, using a restoration abutment platform smaller than the implant platform. MATERIALS AND METHODS: A total of 99 implants were rehabilitated in the maxillary and mandibular posterior regions. A total of 22 implants were rehabilitated in the maxilla and 77 implants in the mandible, using digitally designed customized abutments with Atlantis weborder software, from the commercial house Dentsply Sirona (Dentsply Sirona S.A., Barcelona, Spain), version 4.6.5, adapting the height to the vertical thickness of the mucosa. Clinical and radiographic monitoring begins during the surgical procedure of placement of the implant and ends 12 months afterwards. Crestal bone loss was evaluated through the Carestream® CS8100 3D radiographic equipment. RESULTS: In all cases, the greatest loss of marginal bone occurred between the day of surgery (Tx) and placement of the rehabilitation (To). The average bone loss between both times was greater when the abutment height and vertical mucosal thickness did not exceed 3 mm. Subsequently, bone loss slowed and stabilized at 12 months. CONCLUSIONS: The minimum abutment height and the vertical mucosal thickness are factors to take into account when minimizing peri-implant marginal bone loss, the abutment height having the greatest importance according to the clinical data obtained.

Biological shaping as a conservative alternative for crown lengthening: A review.

OBJECTIVES: The perio-restorative approach to maintaining supracrestal tissue attachment (STA; formerly known as biologic width) is a fundamental goal in modern dentistry. This article aims to review the clinical impact of biologic shaping (BS) as an innovative alternative to traditional crown lengthening procedures, reflecting over two decades of clinical experience. MATERIAL AND METHODS: As a review paper, it is crucial to highlight that BS stands as a unique approach designed to optimize STA while emphasizing minimal to no removal of supporting bone. The review spans over two decades, consistently demonstrating clinical efficacy and predictability. Remarkably, BS focuses on addressing issues such as root concavities, developmental grooves, irregularities, furcation lips, and CEJ offering a remarkable level of clinical precision. RESULTS: The reviewed literature underscores that BS has consistently achieved substantial clinical success in fulfilling its objectives. This method presents a biologically sound alternative to traditional crown lengthening, placing a strong emphasis on the preservation of essential bone tissue and the establishment of durable STA. CONCLUSIONS: The results suggest that BS is a logical and biologically driven approach for maintaining STA, making it a promising alternative to traditional crown lengthening. The method offers a predictable and reproducible way to preserve bone tissue while achieving durable STA. This innovation holds great promise in the field of periodontal and restorative dentistry.

Exploring the Biological Width in Dentistry: A Comprehensive Narrative Review.

Biological width (BW) is the distance established from the junctional epithelium and connective tissue attachment to the root surface of a tooth. It acts as a natural seal protecting the tooth from infections and diseases. The normal dimension of it is 2.04 mm on average. A periodontal probe is used to determine BW in routine clinical practice. Various methods are available for the determination of BW. A diagnosis of BW violation is asserted when the distance is found to be less than 2 mm at single or multiple locations. Gingival health is of utmost importance when considering the long-term health of the tooth as well as any restoration. A plethora of BW violations can lead to a myriad of complications, which are discussed briefly in this article. The article also aims to highlight BW in relation to restorative margins and implants and its clinical assessment as well as shed light on the procedure that can be employed to correct BW violations in dental practice.

The effect of loading time on marginal bone change of implants immediately placed after extraction: a retrospective study.

BACKGROUND: The purpose of this study is to compare and analyze the treatment outcomes between two groups which are both immediately placed implant cases, one is immediate loading, and the other is conventional loading group. METHODS: Medical records of the patients who underwent implant treatment which were immediately placed after tooth extraction were analyzed. Demographic data were collected and by using periapical or panoramic radiographic image, marginal bone level and distant crestal bone level were measured. Marginal bone change over time was analyzed and compared between immediate loading group and conventional loading group. RESULTS: A total of 71 patients, 112 immediately placed implants after tooth extraction were initially involved. Measuring was done with implants which had not failed (81). 10 implants were had failed and removed. The others were excluded because of follow-up loss, absence of radiographic image, etc. Demographic data were collected, and measured values were averaged at each follow-up and showed in linear graphs. CONCLUSIONS: In case of immediate implantation of dental implant after extraction, loading time could affect marginal bone level or biological width of the implant. Immediate loading group showed 0.92 mm (mean value) more bone loss compared to conventional loading group at bone-implant contact points 24 months after implantation. At distant crestal points, there was no noticeable difference in bone change pattern between two groups.

MTA Matrix Technique: Restoration of Teeth with Deep Subgingival Defects Extending Down to the Osseous Crest.

PURPOSE: To present a new restorative technique for the restoration of teeth with deep subgingival hard tissue defects extending down to the osseous crest without additional surgical or orthodontic interventions by combining mineral trioxide aggregate (MTA) and composite material. MATERIALS AND METHODS: The MTA matrix technique starts by deeply inserting a metal matrix as far down to the bone level as possible. The matrix should then be fixated with a matrix holder in its end position. If the matrix band does not seal tightly in the deepest area of the cavity, small portions of MTA are carefully applied to the lower end of the inner side of the matrix band. The MTA acts as a barrier for fluid control. Additional haemostasis is not necessary. Subsequently, the tooth is restored with an etch-and-rinse adhesive and composite resin. The clinical effects were observed in a case series of three patients over a period of 3 to 4.5 years. RESULTS: Excellent outcomes were observed clinically and radiologically. Teeth restored with the MTA matrix technique showed no failures due to the materials used or due to secondary caries or periodontal inflammation after an observation period of 3 to 4.5 years. Probing depths ranged from 2 to 4 mm without bleeding on probing, including the subgingivally restored areas. CONCLUSION: Although only a few casuistic observations are available to date, by using the MTA matrix technique, successful restoration of teeth with subgingival defects down to the alveolar bone crest seems possible without the need of additional surgical or orthodontic measures. Further clinical studies are necessary to confirm the feasibility of this technique.

Periodontal, Functional, and Esthetic Integration of Peri-Implant Soft Tissue: WHS Concept.

The long-term functional success of implant treatment depends on the stability of the crestal bone around the implant platform. The esthetic result is achieved by adequate quality and quantity of soft tissue in the peri-implant area. The soft tissue creates the buffer area that ensures the mechanical and biological protection of the underlying bone. Therefore, it is necessary to maintain in the long term, not only implant osseointegration, but also the integrity of the soft tissue around the sub- and suprastructures of the implant restoration. To create the protective soft tissue area, it is necessary to ensure 3 criteria. This treatment approach will be defined as TWS-soft tissue management: T for thickness, W for width, and S for stability. There are many ways to achieve the first 2 criteria, which are described in the literature. Achieving the third criterion of stability has become possible only recently because of the development of digital treatment planning, surgically guided, and prosthetic-assisted technology that uses a 1-time abutment and its implementation into the dental practice. The purpose of this article is to present with clinical cases a detailed description of each criterion.

The influence of the implant-abutment complex on marginal bone and peri-implant conditions: A retrospective study.

PURPOSE: The design of the implant-abutment complex is thought to be responsible for marginal bone loss (MBL) and might affect the condition of the peri-implant tissues. This the present study aimed to evaluate the influence of the implant-abutment complex on MBL and the peri-implant tissues in partially edentulous patients treated with dental implants and determine the most advantageous design. MATERIALS AND METHODS: A total of ninety-one endosseous implants with different designs of implant-abutment complex [tissue level-TL (n = 30), platform switch-PS (n = 18), and platform match-PM (n = 43)] were reviewed for MBL, Probing Pocket Depth (PPD) and Bleeding on Probing (BoP). MBL was calculated for first year of the insertion and the following years. RESULTS: The median MBL for the PM implants (2.66 ± 1.67 mm; n = 43) in the first year was significantly higher than those for the other types (P =.033). The lowest rate of MBL (0.61 ± 0.44 mm; n = 18) was observed with PS implants (P =.000). The position of the crown-abutment border showed a statisticallysignificant influence (P =.019) and a negative correlation (r=-0.395) on MBL. BoP was found significantly higher in PM implants (P =.006). The lowest BoP scores were detected in PS implants, but the difference was not significant (P =.523). The relation between PPD and connection type revealed no statistically significant influence (P >.05). CONCLUSION: Within the limitations of the present study, it may be concluded that PS implants seem to show better peri-implant soft tissue conditions and cause less MBL.

Factors Influencing Early Marginal Bone Loss around Dental Implants Positioned Subcrestally: A Multicenter Prospective Clinical Study.

Early marginal bone loss (MBL) is a non-infective remodeling process of variable entity occurring within the first year after implant placement. It has a multifactorial etiology, being influenced by both surgical and prosthetic factors. Their impact remains a matter of debate, and controversial information is available, particularly regarding implants placed subcrestally. The present multicenter prospective clinical study aimed to correlate marginal bone loss around platform-switched implants with conical connection inserted subcrestally to general and local factors. Fifty-five patients were enrolled according to strict inclusion/exclusion criteria by four clinical centers. Single or multiple implants (AnyRidge, MegaGen, South Korea) were inserted in the posterior mandible with a one-stage protocol. Impressions were taken after two months of healing (T1), screwed metal-ceramic restorations were delivered three months after implant insertion (T2), and patients were recalled after six months (T3) and twelve months (T4) of prosthetic loading. Periapical radiographs were acquired at each time point. Bone levels were measured at each time point on both mesial and distal aspects of implants. Linear mixed models were fitted to the data to identify predictors associated with MBL. Fifty patients (25 male, 25 female; mean age 58.0 ± 12.8) with a total of 83 implants were included in the final analysis. The mean subcrestal position of the implant shoulder at baseline was 1.24 ± 0.57 mm, while at T4, it was 0.46 ± 0.59 mm under the bone level. Early marginal bone remodeling was significantly influenced by implant insertion depth and factors related to biological width establishment (vertical mucosal thickness, healing, and prosthetic abutment height). Deep implant insertion, thin peri-implant mucosa, and short abutments were associated with greater marginal bone loss up to six months after prosthetic loading. Peri-implant bone levels tended to stabilize after this time, and no further marginal bone resorption was recorded at twelve months after implant loading.

Differential Healing Patterns of Mucosal Seal on Zirconia and Titanium Implant.

Zirconia implants have become an alternative to titanium implants due to several advantages. The zirconia implant is relatively esthetic and highly resistant to bacteria. While biomaterial studies for zirconia implants have considerably accumulated, in vivo studies have not yet progressed. In the present study, the functional and biological properties of zirconia implants were analyzed thorough in vitro and in vivo studies. The proliferation properties of periodontal cells on the discs of machined surface titanium, hydroxyapatite coated titanium and zirconia were analyzed, and zirconia was shown to be favorable. In addition, small implant fixtures that can be applied to the jawbone of mice were manufactured and transplanted to C57BL/6 mice. The adhesion molecules expression patterns in peri-implant mucosa suggest a stronger mucosal seal and more adequate prevention of peri-implant epithelium (PIE) elongation in the zirconia implant when compared with other conventional materials. Differential laminin-332 expression in peri-implant mucosa of zirconia implants seems to regulate the PIE elongation. In conclusion, zirconia was found to be promising and advantageous with regards to the mucosal seal. And biological width (BW) of peri-implant mucosa is more desirable in zirconia implants compared to conventional titanium implants.

[A pilot study on the consistency of biological widths measured by periodontal probe and cone-beam CT].

Objective: To compare the consistency of the biological widths measured by using cone-beam CT (CBCT) and periodontal probe in patients with two different gingival biotypes. Methods: Totally 27 patients [13 males, 14 females, (37.6±13.7) years old], who planned to receive the crown lengthening surgery, were recruited under the inclusion and exclusion criteria in Department of Periodontology, School of Stomatology, The Fourth Military Medical University during November 2017 to June 2018. A total of 40 teeth (14 front teeth, 26 posterior teeth) were involved in this study. The patients were divided into two groups according to their gingival biotypes: thin gingival biotype [5 males, 8 females, (40.2±15.0) years old, 21 teeth] and thick gingival biotype [8 males, 6 females, (35.1±11.9) years old, 19 teeth]. All the teeth were checked before crown lengthening procedures by using CBCT, and the biological widths and sulcus depths were measured during the surgery by using periodontal probes (Hu-Friedy, U S A). The data were recorded and statistically analyzed. Results: There were no significant differences of the biological widths between the two measuring methods amongst all of the 40 teeth [periodonial probe: (1.64±0.26) mm; CBCT: (1.69±0.20) mm], amongst 21 thin gingival biotype teeth [periodontal probe: (1.49±0.19) mm; CBCT: (1.57±0.12) mm] and amongst 19 thick gingival biotype teeth [periodontal probe: (1.80±0.21) mm; CBCT: (1.87±0.18) mm] (P>0.05). There were no significant differences of the biological widths [anterior teeth: (1.59±0.15) mm, posterior teeth: (1.67±0.29) mm, P=0.42] and of the sulcus depths [anterior teeth: (2.00±0.28) mm, posterior teeth: (2.11±0.43) mm, P=0.44] between anterior teeth and posterior teeth. The difference of biological widths, measured by two methods respectively, between thin and thick gingival biotype groups was statistically significant (P<0.01). There were significant differences of the sulcus depths, measured by the periodontal probes, between the thin [(1.93±0.28) mm] and thick [(2.24±0.41) mm] gingival biotype groups (P<0.01). Conclusions: The biological widths measured by CBCT is consistent with those measured by using periodontal probes. The biological widths and the depths of the sulcus of thin and thick gingival biotypes are different.

A Present Day Approach to Crown Lengthening - Piezosurgery.

Maintaining a healthy periodontium during restorative procedures is an indispensable condition for achieving optimal functioning and esthetics. Thus, the knowledge of anatomy, influence of the restorative material and its complement on periodontium is vital. Difficulty in maintaining adequate biological width (BW) is a frequent problem encountered in this type of reconstruction. Crown lengthening is commonly used to maintain the dentogingival complex in optimal conditions and to correct aesthetic defects through a smile design. Piezosurgery, which uses a modulated ultrasonic frequency, permits highly precise and safe cutting of hard tissue. Because of its highly selective and accurate nature, its use may be extended to more complex surgical and interdisciplinary cases. In this case report, we present the contemporary use of piezosurgery for crown lengthening procedure.

Tratamento reabilitador cirúrgico restaurador: relato de caso / Surgical-restoring rehabilitator treatment: a case report

Tendo em vista a abundância de procedimentos realizados envolvendo a inter-relação entre a Dentística Restauradora e Periodontia na Odontologia contemporânea, é preciso salientar a importância da realização de técnicas cirúrgica e restauradora corretas por parte dos cirurgiões-dentistas, assim como na conceitualização de que os tecidos periodontais podem reagir de forma positiva à presença de materiais restauradores adesivos posicionados apicalmente à gengiva, sem a necessidade da recuperação do espaço biológico. O presente estudo teve como objetivo demonstrar a técnica da realização de uma restauração transcirúrgica através de um relato de um caso clínico realizado no Complexo Odontológico do Centro Universitário da Serra Gaúcha (FSG). A paciente foi diagnosticada com uma cavidade subgengival no elemento 16 e submetida à procedimento restaurador transcirúrgico, sendo o ionômero de vidro fotopolimerizável o material restaurador de eleição. Este trabalho evidenciou como os tecidos periodontais podem reagir de maneira positiva à presença de materiais biocompatíveis resultando, inclusive, em um remodelamento ósseo favorável. (AU)

Considering the abundance of procedures performed involving the Restorative Dentistry and Periodontics relationship in contemporary dentistry, it is necessary to emphasize the importance of performing a correct surgical and restorative technique by dental surgeons, as well as in the conceptualization that periodontal tissues can react positively in the presence of adhesive restorative materials positioned apically to the gingiva, without the need of the recovery of the biological width. The present study aims to demonstrate the technique of performing a trans-surgical restoration through a clinical case report performed at the Odontological Complex of Centro Universitário da Serra Gaúcha (FSG). The patient was diagnosed with a subgingival cavity in element 16, underwent a trans-surgical procedure, the light-curing glass ionomer being the restorative material of choice. This work evidenced how the periodontal tissues can react in a positive way in the presence of biocompatible materials, resulting also in a favorable bone remodeling.(AU)

Tooth fragment re-attachment in fracture with biological width violation: case

ABSTRACT: Dento-alveolar traumas are one of the most frequent injuries to teeth, mainly affecting the upper incisors due to their exposed position in the dental arch. In such cases, esthetics, function and phonetics of anterior teeth may be compromised. Furthermore, when there is involvement of the biological width, there is often a poor prognosis. This case report describes the multidisciplinary approach to tooth fragment re-attachment in a fracture with biological width violation. The patient presented with an oblique crown fracture in the maxillary right lateral incisor, extending from the buccal to palatal side, as well as a biological width invasion. The re-establishment of the biological width was obtained by periodontal surgery to achieve clinical-crown lengthening and tooth fragment re-attachment with a glass fiber post to increase retention. After 3 years of follow-up, the rehabilitated lateral incisor remains in good condition, with satisfactory esthetic and periodontal health.

Histological assessment of hard and soft tissues surrounding a novel ceramic implant: a pilot study in the minipig.

OBJECTIVE: The aim of this study was to investigate clinical and soft/hard tissues histomorphological outcomes of a ceramic implant comparatively to a titanium implant in a minipig model. MATERIAL AND METHODS: Eighteen soft tissue level implants (9 Ceramic with ZLA(®) surface as test, and 9 titanium SLActive(®) as control, Institut Straumann, Basel, Switzerland) were randomly placed into the mandible of 6 minipigs (n = 6). Two months later, animals were sacrificed and block biopsies were obtained to assess histomorphological outcomes. Unadjusted paired comparisons, of both groups were performed using the Wilcoxon signed rank test. The Dunnett-Hsu test was used to adjust for multiple comparisons. RESULTS: All implants showed excellent integration into bone and soft tissue. The fBIC (distance implant shoulder to most coronal implant contact) and BIC% (percentage bone-to-implant contact) were for both groups; test: 3.95 mm and 85.4%; control 3.97 mm and 84.3% respectively. No difference in peri-implant mucosa height was found, however, the sulcular epithelium was significantly shorter for the ZrO2 (mean: 0.76, 95%CI: 0.46-1.06) than for the Ti (mean: 1.40, 95%CI: 1.10-1.70) (p = 0.0090). CONCLUSIONS: Within the limits of this pilot study, no difference was found between the ceramic implant with ZLA(®) surface and a titanium implant in terms of bone tissue integration. Furthermore, the epithelial attachment favoured this ceramic implant over titanium.

Application of root angioplasty in crown lengthening surgery / 局解手术学杂志

Objective To analyze the application of root angioplasty in the crown lengthening surgery. Methods A total of 80 patients that corresponding to criteria from January 2013 to December 2015 in repair outpatients of our hospital were selected and received retrospec-tive study,and they were randomly divided into the observation group and the control group according to different surgical methods with 40 ca-ses in each group. The observation group was given root angioplasty and crown lengthening surgery,while the control group was only given crown lengthening surgery. Check-up was performed at 6 weeks postoperatively and 3 weeks after restoration,the condition of root surface cov-ered by the gum,the condition of gingival recession of the restoration and the subjective satisfaction of the patients were observed. Results The average coverage of the observation group was 91. 3%,which was significantly more than 55. 3% of the control group (P<0. 05). The a-mount of the gum covering of the observation group was (3.1 ±1.3)mm,which was significantly larger than (1.9 ±1.0)mm of the control group(P<0. 05). Conclusion Root angioplasty can guarantee blood supply,reduce the damage,but the indication range is small,and it is influenced by many factors,and needs to incorporate the ideas of all sides when used in clinic.

Soft tissue histomorphology at implants with a transmucosal modified surface. A study in minipigs.

OBJECTIVES: To investigate soft tissue histomorphology and quality around implants with a modified transgingival collar surface comparatively to a machined. MATERIAL AND METHODS: Twenty-seven Straumann Standard Tissue Level implants belonging to the following groups (nine of each group): Ti modSLA with machined collar (Ti-M), Ti modSLA with machined, acid-etched surface collar (Ti-modMA), and TiZr modSLA with machined, acid-etched surface collar (TiZr-modMA) were placed in the mandible of six minipigs. After 8 weeks of healing, buccal sections were obtained and processed for histological evaluation. RESULTS: Histometric soft tissue outcomes were similar for the three types of implants. The percentage of connective tissue attached to implant surface and its length was longer at TiZr-modMA with respect to Ti-M implants. The number of inflammatory cells was slightly higher at the TiZr-modMA with respect to Ti-M implant. The percentage of area occupied by perpendicular collagen fibers was slightly higher for the modified surfaces in comparison with the machined. CONCLUSIONS: Modified implant collar surfaces at Ti and TiZr implants showed a soft tissue interface similar to machined. A tendency of increasing number of perpendicular collagen fibers and improved connective tissue contact was found at the modified implant surfaces.
