Abstract
BACKGROUND Search of the English literature yielded no studies assessing the chosen dental treatment following surgical closure of oroantral communication/oroantral fistula (OAC/OAF). The purpose of the present study was to assess factors affecting the decision to rehabilitate the posterior maxilla following surgical closure of OAC/OAF. METHODS Consecutive patients at a single center. A structured form served to collect the data. The differences between groups (cases with versus cases without restoration) were assessed statistically. RESULTS A total of 58/121 responding individuals (62.1% men). Average age 51.57 years. Average waiting time prior to restoration 10.34 months. Most (51.7%) healthy. Most had a dental etiology (60.3%). Thirty-nine (67.2%) patients had a restoration of the posterior maxilla. Most of the patients responded that the reason not to do any restoration is the fear of failure (65.5%). Most of the patients completed the restoration procedure in a private clinic (87.2%). Only one patient (2.6%) reported a complication. Approximately half of the patients had implant supported prosthesis (ISP) following sinus augmentation (48.3%) with delayed implant placement. Most of the patients responded that the reason not to have ISP was the fear of failure (72.7%), and the rest responded because of financial issues (27.3%). For tooth supported restoration, most of the patients responded removable (90.9%). CONCLUSIONS Surgeons generally wait 6-12 months following surgical treatment of OAC/OAF prior to reconstruction with ISP. The chance for complications is low. Healthy women after dental induced OAC/OAF have the highest chances to seek for ISP in such circumstances.

OBJECTIVES Assess the unique clinical and radiological sequelae following oro-antral communications/fistulae (OAC/OAF) due to implant dentistry vs other etiologies. MATERIALS AND METHODS A structured form served to collect data from medical records. All consecutive patients who underwent surgical closure of OACs/OAFs between 2003 and 2020, at a single center were included. Demographic, radiological, clinical, operative and postoperative characteristics were collected. The differences between gro...

Abstract Purpose To evaluate the survival rates of dental implants re-implanted in sites of previous failure, including first, second, and third re-implantations, as well as to investigate the various factors that may affect re-implantation outcomes. Materials and Methods All dental implants placed in sites of previous implant failure were identified, including first, second, and third re-implantations. Survival rates were assessed. Epidemiological and clinical data were collected and analyzed t...

Purpose: To assess the clinical outcomes of replaced implants after removal of failed ones. In addition, associated risk factors that might affect the final outcome of these procedures were also explored. Materials and Methods: An electronic literature search was conducted by two reviewers in several databases for articles written in English up to November 2014. Human clinical trials with a minimum of 10 subjects enrolled that reported clinical outcomes with a mean follow-up period of at least 1...

Objective This study was a retrospective assessment of reentry sinus augmentation compared with sinus augmentation performed for the first time. Study design There were 38 subjects who required sinus augmentation. The study group (17 patients, 21 sinuses) included subjects following failure of a previous sinus augmentation procedure that required reentry augmentation. The control group (21 patients, 21 sinuses) included subjects in which sinus augmentation was performed for the first time. Patie...

Background: The purpose of the present study was to explore the major factors that can affect the decision to replace failed implants. Methods: A retrospective cohort study was conducted on 194 patients who presented following dental implant failure during a 6-year period (2000 to 2006). The collected data included patient characteristics, failed implant characteristics, the anatomic status of the alveolar ridge after failure, and factors affecting the decision to avoid reimplantation. The study...

Objectives: The purpose of the present study was to evaluate the survival rate of dental implants in previously failed implant sites. In addition, factors that might affect the outcome of these redo procedures were also explored. Material and methods: Patients that had failed dental implants, which were replaced with the same implant type at the same site, were included. Data on the failed implants were collected. The same parameters, along with the interval between retrieval and re-implantation...

Failures of endosseous dental implants are rare and tend to cluster in patients with common profiles or risk factors. Clinical trials indicate that factors related to implant devices, anatomy, occlusion,systemic health or exposures, microbial biofilm, host immuno-inflammatory responses, and genetics may increase the risk for im-plant complications or loss. In general, factors associated with the patient appear more critical in determining risk for implant failure than those associated with the i...

ABSTRACT Background Clinicians are confronted with difficult choices regarding whether a tooth with pulpal and/or periapical disease should be saved through endodontic treatment or be extracted and replaced with an implant. Methods The authors examined publications (research, literature reviews and systematic reviews) related to the factors affecting decision making for patients who have oral diseases or traumatic injuries. Results The factors to be considered included patient-related issues (sy...
