In 52 patients, single anterior teeth were extracted and replaced by immediate implants. The peri-implant gap was left either untreated (control) or was grafted and covered with a membrane (test group). After 12 months the horizontal bone resorption was significantly lower in the test group (test sites: 0.

Purpose: To evaluate the influence of sex, implant characteristics, and bone grafting on the survival rate of dual acid-etched (DAE) implants.

Materials And Methods: Patients treated with internal-hex DAE implants for single tooth replacement in a military dental clinic between January 2005 and December 2010 were included in this study. Clinical data related to implant characteristics, implant location, presence of grafted bone, and implant failures were collected.

After tooth extraction, varying amounts of bone resorption occur because of qualitative and quantitative changes at the edentulous site of the alveolar process. The aims of this randomized controlled clinical trial were (1) to compare the postextraction changes in residual ridge dimensions during spontaneous healing with those during socket preservation, (2) to analyze the histologic and histomorphometric aspects of the grafted sockets, and (3) to compare probing procket depth (PPD) and clinical attachment level (CAL) changes at teeth adjacent to extraction sites. Forty-eight teeth were extracted from 41 patients referred for extraction of 1 or more maxillary or mandibular premolars or molars.

This study compared the results following treatment of gingival recessions by a coronally advanced flap procedure alone (CAF) or combined with a bioabsorbable membrane and a demineralized xenograft (GTRF). Sixteen nonsmokers with 20 Miller Class I or Class II buccal gingival recessions at canines or premolars were included in the study. Sites were randomly assigned to either CAF treatment (control, n = 10) or GTRF treatment (test, n = 10) and examined at baseline and at 6 months postoperatively.

The aim of this investigation was to assess the possibility of preserving the buccal and lingual plates of a postextraction socket from resorption using bone filler after tooth extraction. In 10 patients, 10 single extraction sites in the posterior area received a bone substitute. The osteoconductive material was covered by a collagen membrane in all cases.

Among dental implant design alterations, surface modifications have been by far the most investigated topic. Regarding implant surface research, the lack of hierarchical approaches relating in vitro, in vivo, clinical trials, and ex vivo analyses has hindered biomaterials scientists with clear informed rationale guidelines for implant surface design. This manuscript provides a critical hierarchical overview of the in vitro, laboratory in vivo, clinical, and ex vivo methodologies used to investigate the performance of novel biomaterials aiming to allow dental professionals to better evaluate the past, present, and future dental implant surface research.

Purpose: The objective of this study was to evaluate the bone response to a nanothickness bioceramic ion beam-assisted deposition (IBAD) on endosteal implants in a canine model.

Materials And Methods: Alumina-blasted/acid-etched (control) and IBAD-modified (test) implants were characterized by scanning electron microscopy, X-ray photoelectron spectroscopy + ion beam milling, thin-film mode X-ray diffraction, and atomic force microscope. The implants were surgically placed in four dogs' proximal tibiae and remained for 2 and 4 weeks in vivo.

Thick bioceramic coatings like plasma sprayed hydroxyapatite have been shown to increase the overall tissue response and biomechanical fixation of dental implants. However, the presence and potential fracture of a bone-coating-metallic substrate interface at long times after implantation led these implants to fall from favor in clinical practice. The purpose of this study was to evaluate the biomechanical fixation and biological response of Ca- and P-based, 20-50 nm thickness bioceramic deposition on a previously alumina-blasted/acid-etched Ti-6Al-4V implant surface in a dog model.

Introduction: Genetic polymorphisms in the interleukin-1 gene cluster have been associated with the severity of periodontal diseases featured by a variable degree of destruction of connective tissue and bone, such as periodontitis and periimplantitis. This study was aimed to investigate if a link exists between such interleukin-1 gene polymorphisms and the development of gingival recessions during orthodontic treatment in Italian children.

Methods: We evaluated, in 74 young Italian patients of both sexes, the -889 C/T polymorphism of the interleukin-1alpha gene and the -511 C/T and +3954 C/T polymorphisms of interleukin-1alpha gene by polymerase chain reactions-restriction fragment length polymorphism method using NcoI, AvaI and TaqI as restriction enzymes.

Impaction of a maxillary canine is common. Orthodontic realignment is not always the therapy of choice. Instead, the impacted tooth can be extracted and replaced by an implant.

Article Synopsis
  • The study focused on using ultrasonic debridement to effectively remove bacterial biofilm and calculus in patients with severe chronic periodontitis, evaluating the effects of adding povidone-iodine (PVP-iodine) to the treatment.
  • Twenty patients were divided into four treatment groups combining ultrasonic scaling with either PVP-iodine or saline as a solution for subgingival irrigation, and they were monitored for six months.
  • The results indicated that while ultrasonic debridement significantly reduced harmful periodontal bacteria, the addition of PVP-iodine did not enhance the antimicrobial effectiveness compared to using ultrasonic scaling alone.

Objectives: The aim of the study is to compare the peri-implant hard and soft tissue integration around dental implants made of commercially pure (c.p.) titanium or a gold alloy but with the same shape and surface roughness.

The aim of the present study was to evaluate whether it is possible to orthodontically move migrated teeth into infrabony defects augmented with a biomaterial. Three adult patients suffering from chronic periodontitis were treated. Each of the patients presented with an infrabony defect adjacent to a migrated maxillary central incisor.

Objective: Antiseptics and antibiotics delivered either locally or systemically have been used as an adjunct to scaling and root planing procedures in order to control the subgingival biofilm and thereby enhancing the treatment outcome. The results presented in the literature are, however, inconclusive. Povidone-iodine (PVP-iodine) has a bactericidal effect and is effective against most bacteria, including putative periodontal pathogens.

Objectives: The aim of this prospective study was to evaluate dimensional alterations of the peri-implant tissues at single-tooth restorations from the time of implant placement to 1-year post-loading.

Material And Methods: Eleven patients, aged 18-36 years, subjected to single-tooth replacements with implant-supported restorations (Brånemark implant system) in the maxillary anterior region were included in the analysis. The implant installation was performed as a two-stage procedure with a 6-month healing interval.

Background: In cases of advanced periodontal disease with a pathologic flaring of frontal teeth, a combined periodontic-orthodontic therapy may be a reliable approach in order to solve both functional and esthetic problems. The aim of the present study was to evaluate the periodontal tissue alterations following periodontal surgery and orthodontic intrusion in migrated upper central incisors with intrabony defects.

Methods: Ten patients with advanced periodontal disease and an extruded maxillary central incisor infrabony defect at its mesial aspect and probing depth (PD) > or = 6 mm were included in the present study.

The aim of the present retrospective study was to evaluate longitudinal alterations in radiographic bone topography at proximal sites of three-unit implant-supported fixed partial prostheses during the first 3 years after bridge installation, in relation to vertical and horizontal inter-unit distances. The subjects were partially dentate patients who had received implant-supported fixed partial prostheses during the year 1995 at the Brånemark Clinic, Göteborg, Sweden. For inclusion in the study, the patient had to have a three-unit bridge construction supported by three implants in the posterior area of the jaw.

Background: The present study evaluated the healing of enamel matrix derivative (EMD) proteins in the treatment of periodontal lesions with deep intrabony defects.

Methods: Ten deep intrabony defects in 7 periodontal patients were treated and followed for 1 year. The sites had a probing depth (PD) > or = 8 mm; clinical attachment level (CAL) > or = 9 mm, and intrabony component depth > or = 5 mm.
