Filter by:The main objective of this prospective, controlled, and randomized clinical study is to evaluate the peri-implant bone loss of immediately loaded versus conventionally loaded implants with a single prosthesis. A split-mouth experimental design will be used, and the success rate of the installed implants will be determined. Twelve selected patients (corresponding to a minimum of 24 surgical implant sites) will receive endosseous Ti dental implants. The protocol for preparing the surgical sites will be based on the manufacturer's recommendations and bone density. Patients with an initial torque less than 30 N·cm and an implant stability quotient (ISQ) less than 60 will be excluded from the research. Envelopes, indicating which site is the test site, will be opened after the implants are installed. Transfer impressions of the implants receiving immediate loading will be produced so that temporary crowns can be made. Temporary crowns will be installed a maximum of 24 hours after the surgery, by using the torque recommended by the manufacturer. Appropriate occlusal adjustment will be made to ensure minimal contact at maximum intercuspation and absence of contacts during protrusive and lateral excursive movements of the jaw. At baseline (time of implant installation) and 3, 6, 9, and 12 months after implant installation, the following aspects will be evaluated: the initial torque at the moment of implant insertion, Osstell ISQ, pain in the implant when subjected to vertical and horizontal forces, clinical mobility of the implant, crestal bone loss around the implant (as determined by x-ray evaluation), probing depth around the implant, and periodontal pain.
The purpose of this prospective clinical trial is to investigate and identify factors associated with the failure of dental implants within the population rehabilitated with dental implants at the Folktandvården Specialistklinik in Malmö (Spårvägsgatan 12, 214 27, Malmö).

The aim of this study was to compare the efficacy of a diode laser (DL) as an adjunct to conventional scaling in the treatment of mild-to-moderate peri-implantitis. A prospective clinical, radiographic and microbiologic split-mouth study was conducted to test the following null hypothesis; adjunct application of a diode laser, in the conventional treatment of peri-implantitis, are not associated with a statistically significant difference regarding the microbial counts, marginal bone loss and peri-implant parameters.
This study will involve placing donor bone into the back of lower jaw then covering with a newly designed titanium mesh. The mesh will then stay in the mouth for 4 months before it will be removed. Implants will be placed in the newly formed bone. The goal of this study is to test how well using a newly designed titanium mesh and bone particles can grow bone in the back of the lower jaw. The investigators are also checking if the newly formed bone will stay around implants that will have been in use for 12 months.
The present study aimed to evaluate the effects of enamel matrix derivatives either alone or combined with autogenous bone graft applied to intrabony defects in chronic periodontitis patients on clinical/radiographic parameters and gingival crevicular fluid transforming growth factor-β1 level and, to compare with open flap debridement. Our hypothesis is to test whether the use of autogenous bone graft and enamel matrix derivative combination in the treatment of intrabony periodontal defects enhance the clinical, radiographic and biochemical parameters in comparison to the use of open flap debridement alone.
The purpose of the present research is to evaluate the effect of bioactive glass in bone regeneration immediately following extraction of mandibular and maxillary premolars.The hypothesis of the study assumes that this treatment would promote the healing of the extraction socket while preserving both the height and width of the bone. Furthermore, it would allow more effective tooth movement during orthodontic treatment.
GUIDOR Growth Factor Enchanted Bone Graft Substitute (GFeBGS) when used in periodontal surgery will shown greater gum and bone regeneration when compare to bone graft substitute alone. Also, to find the optimal dose.
Purpose: The proposed study will evaluate and compare the clinical response of using bioresorbable collagen membrane alone or defect debridement with erbium Laser irradiation in conjunction with bioresorbable collagen membrane in the treatment of Class II furcation defects in maxillary and mandibular teeth. The study will examine whether there is a superior regeneration potential when the laser energy is combined with membrane defect isolation. Procedure: The study will use 2 groups, a control group and a test group with 16 patients in each group, with severe chronic periodontitis having clinical or radiographic evidence of Class II furcation defects in the buccal or lingual of the mandibular molars or Class II furcation defects on the buccal of maxillary molars. 16 patients will serve as the control group and open flap debridement with bioresorbable collagen membrane will be the mode of treatment. Group 2: 16 patients will serve as the test group and will undergo open flap debridement in conjunction with Er, Cr: YSGG laser irradiation and a bioresorbable collagen membrane will be used.
In this study, the investigators will evaluate the dimensional changes of alveolar bone in the preserved sites in comparison with extraction only conventional healed sockets, as well. 1. Dimensional changes of the alveolar ridge contour after socket preservation in comparison to conventional tooth extraction. 2. Evaluation the stability of implants placed at the preserved sockets. 3. Histological evaluation of newly formed bone at the socket preserved sites in comparison with extracted only healed sites.
