Use of a Collagen Matrix as a Substitute for Free Mucosal Grafts in Pre-Prosthetic Surgery: 1 Year Results From a Clinical Prospective Study on 15 Patients.

Background: The presence of keratinized tissue around dental implants is more than desirable either from a functional and aesthetic point of view, making soft tissue grafting a common practice in implant rehabilitation. Autogenous soft tissue grafting procedures are usually associated with high morbidity. Aim of this study was to assess the efficacy of a xenogeneic collagen matrix as a substitute for soft tissue grafting around dental implants.

Histological Features and Biocompatibility of Bone and Soft Tissue Substitutes in the Atrophic Alveolar Ridge Reconstruction.

The reconstruction of the atrophic alveolar ridges for implant placement is today a common procedure in dentistry daily practice. The surgical reconstruction provides for the optimization of the supporting bone for the implants and a restoration of the amount of keratinized gingiva for esthetic and functional reasons. In the past, tissue regeneration has been performed with autogenous bone and free gingival or connective tissue grafts.

Osseointegrated implants in vertical ridge augmentation with a nonresorbable membrane: a retrospective study of 75 implants with 1 to 6 years of follow-up.

The aim of this study was to retrospectively evaluate 75 implants inserted in vertically augmented bone at the time of or prior to implant placement after 1 to 6 years of prosthetic loading. The study included 21 patients (29 surgical sites). The vertical procedure was performed combining a titanium-reinforced expanded polytetrafluoroethylene membrane with autograft (7 sites), allograft (5 sites), or auto-xenograft (17 sites).

A Retrospective Evaluation of 192 Implants Placed in Augmented Bone: Long-Term Follow-Up Study.

The purpose of the present study was to assess the cumulative survival rate (CSR) of 192 implants placed in association with guided bone regeneration (GBR) procedures to evaluate the long-term predictability of this technique. Moreover, the Kaplan Meier survival analysis was applied to the data in order to evaluate predictors of implant failures, including the source of the graft, the type of membrane, and the timing of implant placement. The CSR of the sample was 95.

Survival of post-treatment canine-to-canine lingual retainers with fiber-reinforced composite resin: a retrospective study.

The aim of the study is to evaluate the long term results of ribbond retainer after orthodontic treatment. One hundred and thirty patients who were orthodontically treated satisfied the inclusion criteria of having received a semipermanent retention were treated with FRC lingual retainers (Ribbond (®)). It was performed a follow up evaluation after 2 years average from the retainer application and any complication or failure was recorded.

Twelve-Year Retrospective Follow-Up of Machined Implants in the Posterior Maxilla: Radiographic and Peri-Implant Outcome.

Purpose: To retrospectively evaluate the survival rate of machined implants in sinus-lifted posterior maxilla after 12 years, with special reference to radiographic outcome and peri-implantitis.

Materials And Methods: From 37 possible candidates, 29 patients with 59 implants were evaluated. Implants were placed in the posterior maxilla in combination with a sinus elevation procedure (27 patients) or 6 months after sinus elevation (2 patients).

Evaluation of postoperative discomfort after impacted mandibular third molar surgery using three different types of flap.

Objective: The surgical extraction of an impacted third molar involves a wide range of consequences such as trismus, swelling, and pain, as well as more significant complications, temporary or permanent, that can manifest altered sensitivity of the tongue or lips. The purpose of this prospective study was to evaluate the effects of three different flaps on postoperative discomfort considering trismus, edema, and pain, after the extraction of impacted third molars. The data derived from the analysis of the surgical trials performed at the Oral Surgery Unit, Department of Surgical, Reconstructive and Diagnostic Sciences, IRCCS Policlinico, University of Milan, directed by Professor F.

Do ultrasonic dental scalers interfere with implantable cardioverter defibrillators? An in vivo investigation.

Objectives: To test the in vivo effects of an ultrasonic dental scaler on various implanted cardioverter defibrillator (ICD) models.

Methods: 12 consecutive patients with ICDs had continuous both electrocardiogram monitoring and device interrogation to detect interferences during the use of an ultrasonic dental scaler.

Results: No interferences were detected by any ICD.

Clinical investigation of mucosal thickness stability after soft tissue grafting around implants: a 3-year retrospective study.

Purpose: To assess the long-term stability of gingival grafts placed around dental implants at the time of second surgery uncovering and to further investigate the association between mucosal thickness (MTh) by demographic variables and clinical investigation.

Materials And Methods: Fourteen patients with submerged dental implants covered by inadequate keratinized mucosa were studied. The subjects underwent a periimplant plastic surgery (PPS) at the second-stage dental implant surgery and free gingival autograft orsubepithelial connective tissue graft were used according to the patients' clinical situation.

Rare bilateral nasopalatine duct cysts: a case report.

The nasopalatine duct cyst (NPDC) is the most common of the non-odontogenic cyst of the jaws. This cysts are usually central or unilateral with no prevalence of side occurrence. The NPDC is the most frequent developmental, nonodontogenic cyst of the jaws.
