The aim of the present study was to establish the efficacy of the socket‐shield technique (SST) for the stabilization of the facial gingival and osseous architecture. An electronic search including the Cochrane databases, EBSCOhost, Medline/PubMed and Web of Science was performed. Articles related to SST for placing dental implants were included. Articles and abstracts not written in English were excluded. The initial literature search resulted in 113 articles related to questions raised. Hand searching of the journals related to implants and cross‐referencing related to SST within the selected articles resulted in 1 more paper. Finally, 20 full texts and abstract of 1 article were included in the present systematic review: 11 case reports, 6 case series, 1 human randomized control trial (RCT), 1 technical report and 2 animal RCT. Recent modifications in SST, along with long follow‐up studies with increased sample size, provided promising results. This systematic review still recommends that SST should not be used in routine clinical practise until a higher level of evidence established. Further RCT on SST are required to establish the clinical efficacy of this technique.

Excessive gingival display is a frequent finding that can occur because of various intraoral or extraoral etiologies. This report describes the use of surgical lip repositioning technique for the management of a gummy smile associated with vertical maxillary excess and hypermobility of the upper lip. The procedure restricts the muscle pull of the elevator lip muscles by shortening the vestibule, thus reducing the gingival display when smiling. Healing was uneventful and follow-up examinations of 10 months revealed reduced gingival display. For patients desiring a less invasive alternative to orthognathic surgery, lip repositioning is a viable alternative.

Gingival recession is one of the most usual esthetic concerns associated with the periodontal tissues. Classification of such condition is important to diagnose, determine the prognosis, and frame the treatment plan. Various classifications have been put forward since decades to classify gingival recession. Miller's classification is the widely used classification among all classifications, but certain drawbacks have been noted in this classification. Therefore, an effort is made to review most commonly used classification systems for gingival recession, and their drawbacks further come up with a proposal of new classification system for gingival recession.

The results showed possible changes in the cellular and molecular components of peripheral blood in patients with GAP compared to periodontally-healthy controls. These changes might represent the contribution of periodontal infections to systemic inflammation in relatively young individuals.

Purpose:The purpose of this finite element study was to compare the stresses, strains, and displacements of double versus single implant in immediate loading for replacing mandibular molar.Materials and Methods:Two 3D FEM (finite element method) models were made to simulate implant designs. The first model used 5-mm-wide diameter implant to support a single molar crown. The second model used 3.75-3.75 double implant design. Anisotropic properties were assigned to bone model. Each model was analyzed with single force magnitude (100 N) in vertical axis.Results:This FEM study suggested that micromotion can be controlled better for double implants compared to single wide-diameter implants. The Von Mises stress for double implant showed 74.44% stress reduction compared to that of 5-mm implant. The Von Mises elastic strain was reduced by 61% for double implant compared to 5-mm implant.Conclusion:Within the limitations of the study, when the mesiodistal space for artificial tooth is more than 12.5 mm, under immediate loading, the double implant support should be considered.

Background:The dimensions of dentogingival junction have been evaluated from autopsy jaw specimens. Previous studies demonstrated variability in histologic biologic width (BW) in periodontal health and mild periodontitis. Few studies have been done on the measurement of clinical BW in periodontitis. BW variation provides implications for selection of surgical or nonsurgical approaches. The purpose of this study was to determine clinical BW in periodontal health and chronic generalized periodontitis and to compare it with histologic dimensions of BW.Materials and Methods:A total of 20 subjects with chronic generalized periodontitis and 20 subjects with healthy periodontium were included in the present study. Plaque index and community periodontal index of treatment needs were scored; moreover, probing depth (PD) and clinical attachment level were measured. Full mouth intraoral periapical radiographs were taken, and digitalized images were obtained to measure the crestal bone level using computerized software.Results:Clinical BW was significantly greater in both healthy and periodontitis groups than previously reported histologic BW of 2.04 mm (P < 0.001). The mean clinical BW was 3.98 mm.Conclusion:Mean clinical BW in both groups was significantly greater than histologic BW and sites with shallow PDs demonstrated greatest BW, suggesting that these sites may be at increased risk for losing significant attachment during surgical procedures.
