Orthodontic tooth extrusion to regenerate missing papilla adjacent to maxillary anterior single implants: A 2- to 7-year retrospective study.

Introduction: Regeneration of the missing papilla adjacent to single implants in the esthetic zone has always been challenging, despite advances in vertical hard and soft tissue regeneration. Orthodontic tooth extrusion has been shown to effectively gain alveolar bone and gingival tissue. This retrospective study evaluated the effectiveness of orthodontic tooth extrusion on regenerating missing papilla between existing maxillary anterior single implant and its adjacent tooth.

Facial Contour Preservation of Anterior Immediate Single-Tooth Replacement With the Socket Shield Technique Versus Connective Tissue Graft: A Case Report.

The socket shield technique and subepithelial connective tissue graft following immediate implant placement with provisionalization had been advocated for peri-implant facial contour and gingival architecture preservation. This case report used three-dimensional volumetric analysis to longitudinally assess the peri-implant facial contour change before and after these procedures. The results demonstrated comparable and acceptable preservation of peri-implant facial contour between the two procedures after 2 years of function.

Effects of cyclic loading on loss of abutment screw torque of angled screw channel single implant crowns on narrow diameter implants.

Statement Of Problem: Screw access channels that emerge on the facial aspect of anterior screw-retained implant crowns can compromise esthetics. Recently, angled screw channels (ASCs) have been developed that can alter screw access channel angulations to improve esthetics. While ASCs can be used on narrow-diameter implants, information is limited on the loss of abutment screw torque on narrow-diameter implants with ASCs.

Facial Mucosal Level Change Following Maxillary Anterior Single Immediate Tooth Replacement in Extraction Sockets With Facial Bone Wall Defects: A 4- to 15-Year Retrospective Study.

An intact extraction socket has been considered a prerequisite for an immediate implant placement and provisionalization (IIPP) procedure. Recent studies, however, have shown successful outcomes when IIPP was performed in sockets with a facial bone wall defect. This retrospective study evaluated the facial implant mucosal stability following IIPP in extraction sockets with a facial bone wall defect in the esthetic zone.

Management of Root Sensitivity following Socket Shield Technique with Anterior Single Immediate Implant Placement and Provisionalization.

Maintaining facial soft tissue contour and inter-implant papilla are challenging for implants in the esthetic zone. To counteract the inevitable hard and soft tissue changes after tooth extraction, the socket shield technique (SST) has been advocated as means to maintain the facial and/or interproximal osseous and gingival architecture. Because SST is a technique-sensitive procedure, various complications related to SST have been reported.

Adhesive residue on the CAD-CAM surgical guide sleeve: A technical report.

Computer-aided design and computer-aided manufacturing (CAD-CAM) surgical guides can be used by the clinician and dental technician to create a definitive cast before surgery, thereby allowing an indirect interim restoration to be fabricated. However, the accurate transfer of the interim restoration from the laboratory to the surgical site requires a precise interface between components. This article reports the prosthetic significance of adhesive residue on the intaglio surface of the CAD-CAM surgical guide sleeve, which can create errors in the implant analog position of the definitive cast.

Residual root preparation for socket-shield procedures: a facial window approach.

Two common complications that occur following immediate implant placement and provisionalization procedures in the anterior maxilla are changes to the facial periimplant soft tissue levels and the facial contours. To counteract these changes, different techniques and treatments have been recommended. The recently introduced socket-shield technique (SST) appears to be a viable treatment option for stabilizing the facial osseous and gingival architecture; however, preparation of the root fragment can present challenges.

Accuracy of Bone Sounding in Assessing Facial Osseous-Gingival Tissue Relationship in Maxillary Anterior Teeth.
