Orofacial-Myofunctional therapy after lingual frenectomy in patient with tongue-tie: a systemic postural approach with mezieres method and postural bench.

AIM: In this study we present the new postoperative oro-myofunctional protocol following frenectomy by atmospheric plasma associated with a systemic postural approach, which determines functional recovery through body symmetry restoration based on the concepts of the French "Mezieres Method" and postural bench. METHODS: A total of 130 patients (76 female, 54 male) affected by ankyloglossia of class III/IV, according to Kotlow's Tongue Tie Classification have been treated with atmospheric plasma followed by oro-myofunctional therapy associated with a systemic postural approach. The overall change, improved/worsened speech, feeding, or sleep has been evaluated through the 10 points Parents Speech Satisfaction (PSS) Score after one week and two months. CONCLUSION: Based on the findings of the current investigation, myofunctional therapy in tongue-tie results in a consistent significant functional ameliorating of feeding capability, speech and sleeping of subject treated as reported with traditional oro-myofunctional therapy.

Microleakage and mechanical behavior of conical vs. internal hexagon implant-abutment connection under a cyclic load fatigue test.

OBJECTIVE: The aim of the present investigation was to evaluate, by an in vitro simulation, the mechanical behavior of the conical vs. internal hexagon under cyclic load and the microleakage of the prosthetic connection of the fixture. MATERIALS AND METHODS: A standardized cyclic loading was performed considering the implant with conical connection (diameter 4 mm - length 10 mm) (CS) and internal hexagon connection (diameter 4 mm - length 10 mm) (IH). The toluidine blue infiltration has been evaluated with the paper cone test. RESULTS: After a total of 5x104 loads, the screw has been removed and the abutment appears solid and stable to the implant fixture for CS, while the IH was unstable. There was no infiltration of the toluidine marker in the connection interfaces of CS implants, while the IH was positive to the paper cone test. CONCLUSIONS: The study data showed that the conical connection showed higher stability compared to the internal hexagon connection under the loading and it is able to prevent bacterial microleakage. This effectiveness should be considered for the long-term maintenance of the peri-implant soft and hard tissues around the fixture.

Volumetric evaluations of the maxillary sinus before and post regenerative surgery.

OBJECTIVE: The purpose of this study was to investigate possible differences in the filling of the various recesses of the maxillary sinus after the procedure of sinus floor elevation in relation with the initial volume of the same and if the sinus volume can influence long-term graft dimensions, by using cone beam computed tomography (CBCT) as diagnostic analysis device. PATIENTS AND METHODS: This study included 32 sinuses corresponding to 16 patients referred for bilateral maxillary sinus augmentation procedures needing to increase the volume of the surgical site with the porcine cortical bone for dental implant placement in the posterior maxilla. The sinuses were analyzed by preoperative and postoperative (15 days and 6 months after sinus surgery) cone beam computed tomography. RESULTS: No statistically significant relations were observed between initial sinus dimensions and the entity of the contraction of the graft between T1 (15 days after surgery) and T2 (180 days after surgery). The behavior was the same either for the large sinus (> 15.65 cm3) and for the small one (< 15.65 cm3). Instead, about the filling of the various sinus recesses, a linear regression model was used to explain the difference between the mean preoperative and postoperative surgical spaces; in most of the samples, the filling of the anterior recess was ~15% of the total volume of the graft, i.e., the minor one among the main recesses. CONCLUSIONS: Our findings suggest that: (1) in the procedure of sinus floor augmentation by a lateral approach with deproteinized porcine bone there are no relations between the initial dimensions of the sinus and the long-term dimensional changes of the graft, and (2) that, among the main recesses of the sinus, the anterior one is generally the less filled.

Rehabilitation of patients with thin ridges by conical expanders and immediate cone morse dental implant: a case report.

BACKGROUND: Horizontal atrophic ridges need a regenerative procedure for implant positioning and fixed rehabilitation. Cone Morse taper implants are characterized by the intimate fitting of the prosthetic interface with the absence of microgaps and micromovements of the interfaces. The aim of this case report was to evaluate the clinical outcome of Cone Morse implant design in split crest augmentation treatment. CASE REPORT: A female patient with partial edentulism of atrophic posterior maxilla was treated for split crest procedure and implant-supported rehabilitation. A full-thickness flap was elevated, and horizontal and vertical osteotomic lines were produced with piezoelectric device. A total of 4 Cone Morse Taper implants (Universal III, Implacil de Bortoli, Brasil) were positioned and the site was grafted with bone substitute and covered by a heterologous membrane. CONCLUSIONS: A complete healing of the surgical site was evident at the follow-up with no evidence of bone resorption. No radiolucency or inflammatory aspects of the treated site were evident in the radiographic control. Simultaneous Cone Morse implants positioning with split crest technique seems to be a promising treatment for posterior maxillary rehabilitation of atrophic edentulous ridges.

Topical hemostatic agents in oral surgery: a narrative review.

Sufficient hemostasis during oral surgical procedures is crucial for successful outcomes and to reduce healthcare resource utilization. The purpose of this narrative review is to give a rational insight into the management of bleeding in oral and dental practice through modern drugs. A narrative literature review has been performed on the present topic identifying all articles on Pubmed/Medline and Google Scholars. Acceptable hemostasis during oral surgery is also required to improve visibility and provide a dry operational area. Many oral surgeons, in their daily practice, encounter problems in controlling postoperative bleeding and use a topical hemostatic agent to promote platelet activation or aggregation to form a stable clot.

Wettability of mg-ha/Chitosan-based membrane surfaces: blood vs. autologous platelet liquid (APL).

OBJECTIVE: The physical and physical chemistry is able to influence the interaction of the scaffolds and bone substitutes with the body fluid and blood. The aim of the present investigation was to evaluate the wettability properties of an Mg-HA Chitosan-based Gel with blood vs. autologous platelet gel. MATERIALS AND METHODS: A total of 6 study groups were evaluated according to the Mg-HA Chitosan-based Gel thickness (1, 2 and 3 mm) and the fluids (blood vs. autologous platelet gel). The biomaterial wettability was conducted through the sessile drop technique. RESULTS: The study findings showed a significant difference in contact angle between the APL and blood groups (p<0.05). The MG-Ha Chitosan-based membrane thicknesses seem to produce no significant effects on contact angles measurement for all groups (p>0.05). CONCLUSIONS: In the present investigation, a similar MG/Ha gel membranes wettability was reported between APL and blood groups. In addition, a high hydrophilicity of MG/Ha gel membranes was reported with a potential advantage in terms of a more effective osteogenic capability in the clinical practice.
