Surgical Nasal Stent Fabrication Using Innovative Multisegmental Cast to Rehabilitate Anatomic and Functional Dynamicity of Upper Airway: A Case Report.

Aim: The purpose of this case report is to provide a simple, efficient, and novel technique for fabricating a nasal stent utilizing a multisegmental cast to rehabilitate the anatomic and functional dynamicity of the upper airway following primary cleft lip and primary rhinoplasty surgery. Background: Nasal deformity is often associated with congenital unilateral or bilateral cleft lip and palate. Despite primary nasal reconstruction at the time of definitive lip repair, the long-term postoperative outcome of the nasal correction frequently falls short of the surgeon's or patient's expectations. This condition is more prevalent in the Asian population due to undeveloped, thin alar cartilage and thick skin. Case description: A 4-month-old female infant was referred from the Department of Plastic Surgery for the fabrication of a nasal stent after surgical cleft lip repair with nasal reconstruction. A customized nasal stent using a multisegmental cast followed by relining with tissue conditioner was planned to minimize relapse of the nasal defect. Conclusion: The technique described in the present case for nasal stent fabrication is simple, cost-efficient and innovative. Postoperative use of this nasal stent helps to maintain the corrected position of the nose after primary lip and nasal correction, resulting in significantly improved esthetic results. Clinical significance: Nasal surgical correction deteriorates over time, especially within the 1st year of surgery due to tissue memory and contraction of the scar tissue. Hence a nasal stent should be worn after the surgery to maintain the corrected nasal form. How to cite this article: Singh S, Rathee M, Alam M, et al.

Effect of conventionally fabricated and three-dimensional printed provisional restorations on hard and soft peri-implant tissues in the mandibular posterior region: A randomized controlled clinical trial.

Background: The purpose of this study was to conduct a randomized controlled clinical trial to compare and evaluate the effect of provisional restorations fabricated by two techniques, namely, conventional and three-dimensional (3D) printing processes on the peri-implant hard and soft tissues over early nonfunctional loaded implants in the mandibular posterior region. Materials and Methods: A randomized controlled clinical trial was conducted across 24 subjects broadly divided into two groups with 12 dental implants each, i.e., GpIC with conventionally fabricated provisional restoration and GpIID with 3D printed fabricated provisional restoration. The prosthetic phase was carried out at 2 weeks, and subjects were evaluated at baseline (at the time of prosthesis placement), 2 months, and 4 months for peri-implant marginal bone level, mucosal suppuration, sulcular probing depth, and modified sulcular bleeding index. Patient satisfaction was assessed using 5-item questionnaires at 4 months. The intragroup comparison for all the data was done using Wilcoxon signed-rank test. The intergroup comparison for all the data was done using Mann-Whitney U-test. The comparison of frequency of responses between GpIC and GpIID was done using Chi-square test. P < 0.05 was considered to be statistically significant. Results: Nonsignificant difference was observed in all the hard and soft tissue parameters between the groups at baseline, 2 months, and 4 months (P > 0.05). Improvement in bleeding on probing was found to be greater around dental implants restored with 3D printed provisional restoration than dental implants restored with conventionally fabricated provisional restoration from baseline to 4 months of follow-up, and the difference in finding was statistically significant (P < 0.05). There was a statistically nonsignificant difference seen for the frequencies between the groups (P > 0.05) for all questions related to patient satisfaction. Conclusion: The effect of conventionally fabricated and 3D printed provisional restorations on peri-implant hard and soft tissues was comparable to each other on an early nonfunctionally loaded implant in the mandibular posterior region.

Comparative evaluation of implant stability and crestal bone level between tapered and cylindrical implants in the posterior regions of the mandible: A prospective, randomized, split-mouth clinical trial.

Purpose: To compare the clinical outcome of tapered and cylindrical implants placed in the posterior region of mandible by measuring implant stability and crestal bone level at the healing period. Materials and Methods: A prospective clinical study was conducted on 15 patients who were included in the study based on the inclusion and exclusion criteria. A total of 30 dental implants were placed in both groups: 15 implants in Group I (tapered implants) and 15 implants in Group II (cylindrical implants) in the posterior region of mandible. Implant stability assessment by periotest was done at the time of implant placement (baseline) and after 3 months. The crestal bone level was measured with the help of radiovisiography (RVG) at the time of implant placement (baseline) and at 3 and 6 months. Results: At baseline, there was statistically significant (P < 0.01) difference in primary implant stability. Tapered implants had higher primary implant stability than cylindrical implants. However, at 3 months, there was no statistically significant (P > 0.05) difference in the secondary implant stability of both the groups. Also, the crestal bone level on the mesial and distal sides of dental implant for tapered and cylindrical implants was statistically nonsignificant (P > 0.05) at all time intervals, that is, at baseline and at 3 and 6 months. Conclusion: Tapered implants had higher primary stability than cylindrical implants, and no difference was found in secondary stability. The crestal bone level was similar for both groups during early healing and early post-loading periods.

Surgical Assistance for Favorable Outcome Achieved through Presurgical Nasoalveolar Molding Using Innovative Impression Technique: A Case Report.

Aim: The aim of this case report is to highlight the importance of presurgical nasoalveolar molding (PNAM) in cleft lip and palate (CLP) cases and its impact on primary surgical outcomes. Background: Cleft lip and palate (CLP) is one of the most common congenital malformations of the maxillofacial complex. Of all congenital malformations, it ranks third and has a multifactorial etiology. Such anomalies can have several consequences, such as impaired suckling, defective speech, deafness, malocclusion, gross facial deformity, and bring tremendous stress on the entire family. Surgical correction is required to restore the form and function of the affected area; however, surgery has to be usually deferred due to the age of the newborn patients. Case description: A 12-day-old neonate born with a bilateral cleft of lip and alveolus was referred from the Department of Plastic Surgery. PNAM was planned in consultation with the plastic surgeon. A customized nasoalveolar molding plate was fabricated, and tissue molding was carried out. Following nasoalveolar molding, primary surgical repair was done. Conclusion: Significant reduction in cleft width, approximation of soft tissue of the lip, and improvement in nasal tip alignment were achieved following PNAM. It favorably positioned the tissue segment and minimized the extent of the local tissue dissection and advancement. The synchronous prosthodontics and surgical treatment resulted in optimal treatment outcomes. Clinical significance: The higher level of estrogen and hyaluronic acid in the newborn that remodels the cartilage can be utilized through the light application of forces, and hence hard and soft tissue molding can be achieved without surgery. PNAM acts as a promising adjunct prior to primary surgical closure of the CLP. Thus, PNAM immediately after the birth can serve to significantly augment the surgical outcomes and the extent and/or the number of surgeries can be reduced.

Rehabilitation of orbital exenteration postsquamous cell carcinoma of orbit using magnet retained two-part silicone and acrylic prosthesis: A case report.

ABSTRACT: Orbital exenteration performed to treat various neoplasms or nonmalignant diseases results in functional, aesthetic, and psychological issues for the patients. If reconstructive surgery is not possible or not desired by the patient, an orbital prosthesis is an excellent choice for cosmetic and psychological rehabilitation. An orbital prosthesis is aesthetic, durable, long lasting, cost-effective, and most importantly retentive. The present case report describes the rehabilitation of an orbital exenteration postsquamous cell carcinoma using a two-part prosthesis, in which retention is achieved by a combination of relining of anatomic undercuts and magnets.

Resin-bonded bridge as a simplified approach to restore missing teeth in esthetic zone by conventional and digital techniques.

One of the most challenging esthetic concerns in dentistry is conservative replacement of the missing anterior teeth. Although implants are considered to be a better treatment option for rehabilitation of such patients, resin-bonded bridges (RBBs) can conservatively restore the missing teeth and have thus gained popularity over the years. It consists of an artificial tooth with a wing-like extension that is cemented to the adjacent teeth. There are various types of RBBs among which Maryland bridge is the simplest and the popular most due to its micromechanical retention enabled by acid etching of both tooth and metal retainer. It can be fabricated by various techniques and materials. In this case reports, we have discussed about two unique designs of Maryland bridge fabricated by two different materials (Porcelain-fused metal and Graphene) and utilizing two different techniques (conventional and digital).
