Conventional avulsion versus less traumatic extraction of ankylosed roots with a magnetoelectric device in anterior maxillary areas.

The analysis aimed to compare two different single-tooth extraction surgical approaches in anterior maxillary areas of the ankylosed teeth: less traumatic magneto-electrical (mag) versus conventional tooth extraction (con) in minimizing the adverse effects on post-extractive sockets. Parameters of clinical interest such as intra-surgical fracture of the buccal bone plate, presence of postoperative inflammation, and application of stitches were acquired from medical records. The data were subjected to Pearson's χ analysis or to Fisher's exact test with significance at 0.

Specific use of the implant stability quotient as a guide to improve healing for patients who had undergone rehabilitation with fixed implant-supported dental prostheses.

Purposes: to develop a clinical approach to evaluating osteointegration around bone implants and try to determining which was the correct time of implant loading in different edentulous indications, that is, either properly positioned implants or implants "at risk", generally referred to as implants having increased probability of failure (namely those for which primary stability had been achieved via a time-consuming surgery).

Materials: Several implant-supported rehabilitation strategies, with or without bone augmentation procedures, were performed in the upper and lower arches: From 2 to 5 months following implant placement, the prosthetic restorations were performed. A resonance frequency analyzer allowed clinicians to measure intraoperative and postoperative implant stability, then the values of the implant stability quotient, ISQ, ranging from 0 to 100, were registered.

Volume assessment of the external contour around immediate implant with or without immediate tooth-like crown provisionalization: A digital intraoral scans study.

Purposes: To examine differences between immediate and delayed dental implant loading in maxillary aesthetic areas.

Methods: In this retrospective controlled analysis, 43 subjects who underwent immediate placement of the dental implant in a post-extraction socket were ranked into either immediate (24 implants loaded with non-occlusal tooth-like profile provisional prostheses fabricated by virtual diagnostic impressions and an in-office dental milling machine) or delayed group (19 implants loaded with conventional cover screws and secondary intention healing). Intraoperatively and then four months later, scans of the external layers were acquired with an optical scanner.

Long-Term Outcomes of Implants Placed in Maxillary Sinus Floor Augmentation with Porous Fluorohydroxyapatite (Algipore FRIOS) in Comparison with Anorganic Bovine Bone (Bio-Oss) and Platelet Rich Plasma (PRP): A Retrospective Study.

Purpose: The objective of this retrospective study was to evaluate the long-term clinical outcomes of bone regeneration procedures using algae-derived plant hydroxyapatite (Algipore FRIOS) compared with demineralized anorganic bovine bone (Bio-Oss), in combination with autologous blood-derived PRP.

Materials And Methods: Partially edentulous patients with severe atrophy of posterior maxillary treated by means of the split bone technique in a two-stage grafting procedures were observed for up to seven years after implants placement. After surgeries, the natural porous fluorohydroxyapatite (FHA) (Algipore FRIOS; Group, = 29) or anorganic bovine bone (Bio-Oss Group, = 28) with autogenous bone in a 50:50 composite ratio with PRP, were administered in a 2.

Interpositional bone grafts in the posterior mandibular region: a report on six patients.

The purpose of this study was to evaluate treatment of resorbed posterior mandibles with interpositional bone grafts (the "sandwich" technique) and implant-supported prostheses. Six consecutive patients with resorbed posterior mandibles (seven sites) were 4reated by the sandwich osteotomy technique with an interpositional bone graft harvested from the iliac crest. Vertical bone height was measured before surgery and 3 to 4 months later, prior to implant placement, on computed tomography scans to evaluate the augmentation obtained.

Impact of implant surface and grafting protocol on clinical outcomes of endosseous implants.

Purpose: The objectives of this study were to (1) evaluate the survival of implants placed in maxillary sinuses augmented with a 70:30 mixture of autogenous bone and anorganic bovine hydroxyapatite (Bio-Oss) at 1 and 5 years, (2) observe the difference in survival rate between 1-stage and 2-stage procedures, and (3) compare the survival rate of rough-surfaced implants with that of machined implants.

Materials And Methods: A total of 30 consecutively patients (48 sinuses) with Cawood and Howell Class V and VI atrophy were evaluated. Lateral osteotomy techniques were used in all cases.
