Filter by:Studies on facial trauma are essential to establish an appropriate treatment approach, assess the ability to restore functions and seek ways of prevention. Among craniofacial injuries, fractures of the zygomatic complex are the most frequent, occurring in 25-30% of cases. Statistical analysis shows that traffic collisions (41%), domestic accidents (23%) and sports accidents (18%) are the main causes. Dental implants have emerged as a rehabilitative alternative for these patients, being considered the first choice for individuals who have lost all or part of their dental arch. In addition to providing a better quality of life, it reconstitutes masticatory function, self-esteem and phonetics. Understanding the importance of evaluating the performance of dental implants and considering the responsibility for the health of patients, there was a need to evaluate the effectiveness and safety of the Standard Internal Hexagon Implant System (HIS), Large Internal Hexagon (HIL), Flexcone (FC) , Mini Flexcone (FCM) and Morse Internal Hexagon, from DSP. In this prospective study, 1053 implants will be included. To be eligible, patients can be of both sexes, be 18 years of age or older, any race and gender, have partial or total tooth loss, present good local and general health conditions and psychological disposition to undergo common oral surgery procedures. under local anesthesia and healthy edentulous region as they will be subsequently submitted to surgical procedures using the DSP Implant System. Electronic data collection and management will be performed using the REDCap software, with categorical variables being described as absolute and relative frequencies and continuous ones being tested for normality using the Shapiro-Wilk test. Osseointegration percentages between 30 days and 6 months will also be calculated. Other efficacy outcomes and incidence of adverse events will be estimated with 95% confidence intervals. As a result, from the strengthening of product evaluation actions, it is expected to demonstrate that the implant has a good safety and efficacy profile to be offered to the population.
A triple function scan Body were done on healed dental implant, thus simplifying the workflow for full arch cases and reducing the number of visits to only 3 visits. In this technique, scan bodies were utilized for implant position scanning, facial scan alignment and as stoppers for jaw relation capturing as scan bodies were used as stoppers for jaw relation registration.
The purpose of the study is to investigate the significance difference between low intensity pulsed ultrasound (LIPUS) versus low-level laser therapy (LLLT) on osseointegration, soft tissue healing, pain pressure threshold and oral health related quality of life in patients post dental implant surgery.
The aim was to compare two protocols for immediate implants with fixed provisional restoration, no grafting (trimodal approach=TA) versus grafting both osseous gap and peri-implant mucosa (trimodal approach with modification of the osseous and mucosal compartments =TAOM) by measuring the soft tissue changes overtime. The periodontal phenotype was registered, to investigate a relationship between its thickness and the clinical outcomes.
For free hand dental implant placement, a key difficulty is to accurately control the position. Improving precision of dental implant placement is considered important for safety and efficacy of tooth replacement with dental implants. The goal of this randomized controlled trial is to compare the positional implant accuracy, and patient reported outcomes comparing two methods of implant placement: the use of a robotic assisted surgery and freehand surgery. Patients requiring single tooth replacement with a dental implant will be digitally planned using a CBCT and an intraoral digital scan. Subjects will be randomized to one of the two treatment modalities based on the plan. The accuracy of placement will be assessed evaluating the difference between the planned and the actual position using a CBCT immediately after surgery. Subjects will be followed up for one year to assess both patient reported and professional outcomes.
For free hand dental implant placement, a key difficulty is to accurately control the position. Improving precision of dental implant placement is considered important for safety and efficacy of tooth replacement with dental implants. There are 3 available methods to improve implant position according to a digitally constructed prosthetically guided plan: the use of a 3D printed static guide, the use of a dynamic navigation system or the use of a robotic system. The goal of this randomized controlled trial is to compare the positional implant accuracy, the surgical time, and patient satisfaction among three methods of digital guidance: the use of a 3D printed static guide, dynamic navigation, and robotic assisted surgery. Patients requiring single tooth replacement with a dental implant will be digitally planned using a CBCT and an intraoral digital scan. Subjects will be randomized to one of the three treatment modalities based on the plan. The accuracy of placement will be assessed evaluating the difference between the planned and the actual position using a follow-up scan taken at the end of the surgery. Subjects will be followed up for one year to assess both patient reported and professional outcomes.
Dental implants have been on the market for several years and they are routinely used to replace single/multiple missing teeth with a high success rate. However, there is still a limited number of studies comparing hydrophilic titanium and zirconia implants. In addition, there is no data available on the signalling pathways and the expression of healing biomarkers involved in the early stages of osseointegration around zirconia surface implants placed with guided bone regeneration (GBR). This study aims 1) to describe and compare the early wound healing molecular pathways, and the 2) vascularization patterns of mucosal tissues after the placement of hydrophilic titanium or zirconia implants with simultaneous guided bone regeneration (GBR). In this study, the investigators will assess the expression of inflammatory, angiogenesis and osseous biomarkers of PICF at 3, 7, 15 and 30 days after the placement of hydrophilic titanium or zirconia dental implants with simultaneous GBR and of saliva at day 1, 3, 7, 15 and 30.
The aim of this randomized controlled trial is to evaluate whether is better to place KS Osstem Implants with BA or SA surface placed in patients with type 2 diabetes, and to compare clinical and radiographic data.
To compare the clinical and radiographic outcomes of two different implant systems with different implant-abutment connection: Osstem TS III (control group) versus Osstem KS (study group).
Vertical bone height reduction after extraction in the posterior maxilla is inevitable and complicates the treatment plan. Crestal sinus elevation, using implants and different grafting procedures are considered some of the proposed treatment protocols. Ever since the introduction of implant dentistry and implant placement in the posterior maxilla has been a dilemma. The choice of the type of bone, anatomical landmarks and reduced remaining bone height are all obstacles faced when placing implants in this area. Vertical bone height reduction occurs post extraction of the maxillary molars and premolars by maxillary sinus pneumatization. Many protocols were suggested to overcome this phenomenon; placing short implants, 2nd premolar occlusion and finally maxillary sinus elevation. A recent systematic review evaluated osteotomes mediated sinus floor elevation with or without grafting material. It concluded a high long term survival rate in both procedures, however only one comparative study was used in the analysis that involved 12 participants only. Another systematic review assessed the survival of implants placed with lateral versus crestal sinus approach in 4-8 mm ridge height. It concluded that the ability of the less invasive crestal sinus approach to replace one-stage lateral approach, however, only one randomized control trial was presented that involved 4o patients, and were followed-up for 5 years. This emphasizes the gap of knowledge in literature with high quality evidence concerning these approaches. The purpose of the present study is to evaluate the radiographic vertical gain in bone height as well as the implant stability after implant placement without the use of bone grafts in posterior maxilla following sinus elevation using the crestal implant approach technique.
