Filter by:Materials and methods: fourteen patients were selected according to the inclusion criteria, the participants were stratified equally into two groups, patients were assigned to receive either monoplane or lingualized occlusal schemes to their overdentures. For each patient placement of two mini-implants in the mandible at the canine region was done, bar joint attachment was used to splint the mini implants. Each implant was 2.5 mm in diameter and 10 mm in length. T-scan occlusal load analysis records were done in centric occlusion , the records was used to analyze the biting force of the denture as a Full Closure Force Movie recording, then Time vs. Force Graph of that Force Movie is accomplished. T-scan records were taken three times for each patient in the two groups ,Immediately after loading ,three months and six months of loading.
Twelve participants with edentulous alveolar crests in the distal portion of the arches will be included in the study. At least two implant sites will be identified in each patient and will be sub-prepared with drills or sonic instruments. One site will be used as a test and one as a control where experimental mini-implants will be installed. Reconstructive surgical procedures will be applied at the biopsy sites.
A multicenter prospective observational study in which aim is to illustrate the clinical outcome of dental implants "Kontact N"; and the effects of its nanostructured surface on the osseointegration and secondary stability without increasing the rate of peri-implantitis. All the enrolled patients will be eligible for one or multiple implant-supported fixed restoration(s) according to the routine clinical practice and the manufacturer's instruction for use.
The present retrospective study aims at assessing the clinical effects of a novel implant site development (Extraction site development - XSD) technique after tooth extraction compared with extraction alone in patients requiring dental implant placement following healing of extraction sockets.
1. Hypothesis/Specific aims The aim of the present study proposal is to validate an implant treatment concept in the edentulous upper maxilla using four implants-supported locators abutments to retain removable prosthesis. Specific aims: - The primary objective of the study is to evaluate the implant and prosthodontics success rates of the proposed implant treatment approach after a follow-up period of 1, 3 and 5 years as well as the biological and prosthodontics complications. - The secondary objective is to assess the evolution of patient centered outcomes with the suggested treatment in the maxilla. Oral health-related quality of life (OHRQoL) and patients' satisfaction relating to their prostheses will be considered. - The third objective will be to compare the implant, prosthodontics and patient-centered outcomes according to the implant distribution; 4 anterior to maxillary sinus (ANT) versus 2 anterior implants and 2 implants in the maxillary tuberosity (POST). Hypothesis: - Implant survival rate using this treatment concept is similar to restoration with implant-supported fixed prosthesis, based on published data. No difference of implant survival rates is found between ANT and POST implant distribution. - Prosthodontics survival rate using the following treatment concept is similar to the ones found with a bar, based on published data. The ANT implant distribution causes fewer prosthodontics complications compared to the POST implant distribution. - There is a significant improvement in OHRQoL and patient satisfaction compared to the baseline OHRQoL observed with a conventional removable denture. The levels of improvement OHRQoL and patient satisfaction are similar for ANT and POST implant distributions.
Aim of the present investigation will be to evaluate the role of a bovine-bone mineral and a collagen membrane as ridge augmentation procedure following tooth extraction. 20 consecutive adult patients, requiring tooth extraction in the frontal area of the upper and lower arch maxilla (from second premolar to second premolar), will be enrolled into the study. After tooth extraction, sockets will be randomized and divided into two groups: in Group A the socket will be grafted with Bio-Oss Collagen , in Group B the sockets will be grafted with BioOss granules (small granules). The graft will be covered with porcine collagen membrane (BioGide). Then, the flap will be sutured. MEASUREMENTS: The end of the study will be fixed at the 6 months evaluation after tooth extraction. Impression will be taken before tooth extraction and after 6 months in order to create cast models. On the cast models, using reference PVC (polyvinylchloride) guides, the horizontal dimension of the soft tissues will be measured. One measurement per tooth will be recorded, at T0 (before extraction) and T2 (after 6 months). A 3D radiological image, using the CBCT technique, will be obtained at the end of the surgical stage T1 (extraction + bone graft) and after 6 months of healing. Superimposition will be performed in order to measure hard tissue remodelling. After six months (T6), a a biopsy specimen will be also harvested for that augmented extractions sockets on which an implant installation has been previously planned.
