ABSTRACT
Since the use of dental implants is continuously increasing, it is imperative for dental practitioners to understand the nature and treatment of peri-implant diseases. The purpose of this manuscript is to comprehensively review peri-implant diseases, their characteristics, as well as their non-surgical and surgical treatment. To that end, the current literature was searched and a narrative review was conducted. It is essential that the case definitions described in the 2017 World Workshop on the Classification of Periodontal and Peri-implant Diseases and Conditions are used to diagnose and classify peri-implant health, peri-implant mucositis and peri-implantitis. While recent epidemiologic studies on peri-implant diseases exist, there is great heterogeneity in the definition of these conditions. Several risk factors and indicators are reported in the literature, with smoking and diabetes being the most universally accepted. In peri-implant mucositis, non-surgical treatment seems to be sufficient. However, for the treatment of peri-implantitis, a surgical approach, which includes open-flap debridement, apically positioned flap and guided bone regeneration, is considered more appropriate. A great variety of adjuncts to mechanical treatment have been reported with controversial results. Finally, studies comparing results from different peri-implantitis treatments are warranted in randomized controlled clinical trials in order to provide stronger evidence-based approaches.
ABSTRACT
The aim of this present prospective study was to evaluate the outcomes of the multiple coronally advanced flap (MCAF) with a site-specific application of connective tissue graft (CTG) for the treatment of multiple gingival recession defects with or without the presence of noncarious cervical lesions (NCCLs). Analysis of periodontal conditions was performed in order to determine if the cementoenamel junction (CEJ) restorations could affect adequate plaque control as well as maintenance over time. A total of 93 gingival recessions were treated, 61% of which presented a NCCL restored with composite resin positioned 1 mm apical to the position of the anatomical CEJ. The surgical treatment involved MCAF+CTG for 54 sites and MCAF alone for 39 sites. At 12 months, complete root coverage (CRC) and periodontal parameters of restored and nonrestored teeth were assessed, and the differences between the two groups were not significant. It can be concluded that the proposed treatment modality does not produce a negative effect on periodontal condition and amount of CRC, thus resulting in a satisfactory esthetic result.
