Feasibility of Alloplasts in Extraction-Socket and Sinus Augmentation Procedures.

Thirty-eight patients (aged 25 to 74) requesting extraction-socket and sinus augmentation procedures (27 and 11 patients, respectively) prior to implant placement volunteered to participate in this case series protocol. Surgical sites were grafted with either biphasic calcium phosphate (BCP) + collagen (for extraction-socket augmentation) or BCP with a collagen barrier membrane (for maxillary sinus augmentation). All patients completed the 1-year postloading follow-up, which consisted of clinical and radiographic evaluations.

Marginal bone and soft tissue behavior following platform switching abutment connection/disconnection--a dog model study.

Objective: The effect on the marginal peri-implant tissues following repeated platform switching abutment removal and subsequent reconnection was studied.

Material And Methods: Six adult female Beagle dogs were selected, and Pm3 and Pm4 teeth, both left and right sides, were extracted and the sites healed for 3 months. At this time, 24 bone level (BL) (Straumann, Basel, Switzerland) Ø 3.

A novel approach to preserve the buccal wall in immediate implant cases: a clinical report.

The aim of this article is to present a novel approach to preserve the buccal wall when performing immediate implants. After immediate implant site preparation, the socket is filled with Bio-Oss collagen and trimmed in a cone form to closely adapt to the buccal wall. Then, the implant is placed with low-rotation-speed condensing Bio-Oss collagen buccally.

Immediate implants and immediate loading in periodontally compromised patients-a 3-year prospective clinical study.

To avoid the necessity of a removable provisional prosthesis, and therefore preserve the patient's functional outcome, esthetics, and quality of life, a clinical protocol was developed to approach periodontally compromised patients presenting a full-arch irreversibly lost dentition: full-arch extraction and immediate replacement with a provisional acrylic resin implant-supported fixed partial denture (FPD). A total of 23 periodontally compromised patients (11 women, 12 men; 4 smokers, 4 controlled diabetics) were included in this study. Pretreatment casts were taken and vertical dimension of occlusion was determined.

Biological width following immediate implant placement in the dog: flap vs. flapless surgery.

Objective: To assess the marginal soft tissue healing process after flap or flapless surgery in immediate implant placement in a dog model.

Material And Methods: This study was carried out on five Beagle dogs. Four implants were placed in the lower jaw in each dog immediately after tooth extraction.

Tapered implants: from indications to advantages.

Tapered implants have become routine for immediate implant placement after tooth extraction. It seemed extremely advantageous to use tapered implants in type 4 bone, where primary stability is difficult to achieve. The authors established a surgical implant placement protocol to be followed in areas where type 4 bone and a wide bone ridge (> or = 8 mm) are present.
