ABSTRACT
Following the extraction of a compromised tooth, the edentulous alveolar ridge undergoes physiologic bone remodeling, which may create a bone volume too deficient for implant placement. Guided bone regeneration (GBR) provides a predictable treatment option to increase the alveolar bone volume for implant placement, but a soft or hard tissue deficiency may remain even after this augmentation procedure has been completed. These deficiencies can be especially challenging in the esthetic zone, where patient expectations and esthetics often determine the satisfaction of the treatment outcome. This paper presents a case report of a xenograft bone substitute used at the second-stage surgery and abutment insertion to provide a solution to these deficiencies even after the patient had undergone a GBR procedure, thus improving the esthetic and functional outcomes of the final implant-supported restoration.

Different techniques have been introduced when replacement with an implant is planned after tooth extraction. The conventional approach consists of waiting 3 to 4 months before implant placement. However, many other options are available for implant placement, including immediate implant placement (IIP), IIP and immediate provisionalization (IIPIP), and early implant placement (EIP). When the ridge is deficient, guided bone regeneration (GBR) with simultaneous implant placement is often performed. However, this procedure has potential for postoperative complications and patient discomfort, as well as an extended treatment time. The recent introduction of the Customized Alveolar Ridge-Splitting (CARS) technique can help avoid many of these problems and treat atrophic ridges that will require two or three GBR surgeries. The purpose of this case report is to demonstrate the step-by-step surgical and restorative procedures for the CARS technique and present histologic data of the new bone generated utilizing this technique.

A link between periodontitis and cardiovascular disease has been reported in the literature. For this systematic review, the keywords "cardiovascular disease" (CVD) were combined with "periodontitis" and "peri-implantitis" and were used to search for literature published on MEDLINE and PubMed between 1990 and 2020. Hand searching was also performed. A total of 206 articles were identified, 51 of which were reviewed. A link between periodontal disease and CVD can be explained by both the infection and inflammatory pathways. Interventional studies on the treatment of periodontal disease related to CVD have shown conflicting results. Therefore, based on published studies, CVD should presently be considered a comorbidity of periodontitis (with an association but no direct cause and effect documented). The association of CVD with peri-implantitis has too few studies to draw any conclusions. More studies are necessary before any conclusions can be made between CVD and periodontitis and CVD and peri-implantitis regarding possible links and the extent of association.
