Multidisciplinary Approach to Smile Restoration: Gingivoplasty, Tooth Bleaching, and Dental Re-anatomization.

This article reports on the case of a patient who underwent a multidisciplinary treatment in smile design that entailed dental cosmetic techniques involving esthetic periodontal surgery, teeth bleaching, and re-anatomization of the upper incisors. The male patient presented with a chief complaint of an excessive gingival display while smiling, as well as small, darkened teeth with spaces between them. After diagnosis and patient consent, therapy began in the following stages: periodontal plastic surgery with probing, bleeding points delimitation, beveled incision, removal of the gingival band with periodontal curettes, and finishing with an electric scalpel. After 21 days following surgery, dental bleaching using a combined technique that included two sessions of in-office bleaching (35% hydrogen peroxide) and 2 weeks of at-home bleaching (carbamide peroxide 16% for 4 hours per day) was carried out, followed by dental re-anatomization using resin composite. Diagnostic waxing, mock-up, fabrication of a palatal silicone index, incremental sculpturing, and structuring the restoration of the palatal shell to the vestibular surfaces was then completed, followed by occlusal adjustment, finishing, and polishing. The multidisciplinary intervention was fundamental for the accomplishment of the proposed treatment that combined biological, functional, and esthetic concepts.

Influence of Diabetes on the Survival Rate and Marginal Bone Loss of Dental Implants: An Overview of Systematic Reviews.

We aimed to conduct an analysis of the systematic reviews (SRs) in literature about the implant survival rate (ISR) and marginal bone loss (MBL) in diabetic and nondiabetic patients. This work was registered in The International Prospective Register of Systematic Reviews (CRD42018095314) and was developed following Preferred Reporting Items for Systematic Reviews and Meta-Analyses and the Cochrane Library Handbook. A search was performed on PubMed, Cochrane, Scopus, Embase, and LILACS. The PICO (problem/patient/population, intervention/indicator, comparison, outcome) question was "Do the survival rates of dental implants and marginal bone loss differ between diabetic and nondiabetic patients?" A total of 130 articles were retrieved. After eliminating repetitions, 118 were reviewed. Finally, 6 SRs were included. All the reviews indicated that there is no effect of diabetes on the ISR; however, a negative effect of the disease can be observed in MBL. Analysis of the quality of the studies was performed using the assessment of SRs in dentistry (Glenny Scale) and Assessing the Methodological Quality of Systematic Reviews (AMSTAR 2). Glenny Scale showed a moderate to high quality of the included studies. In contrast, AMSTAR 2 pointed out a critically low level for 4 studies, with no study fulfilling the criteria for high quality. It may be concluded that there is no effect of diabetes on the ISR; however, a negative effect of the disease can be observed on MBL.
