Filter by: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.
After jaw resection, free vascularized bone flaps are frequently used for repairing maxillofacial defects. Simultaneous dental implantation is more preferable to secondary implantation as it saves the patients from going through a second surgery after recovering from the first one. In this study, the aim is to preliminarily evaluate the clinical outcome of simultaneous dental implants in vascularized bone flaps in jaw reconstruction using patient-specific surgical plates and 3-in-1-PSSG. The objectives of this study were: 1) to investigate the intraoperative success rate; 2) to measure the accuracy of dental implants position; and 3) to assess implant survival rate and postoperative adverse events.
The aim of the present study is to compare the rate of new bone formation after sinus floor elevation with or without perforation of the cortical sinus floor prior to insertion of augmentation material. Twelve patients requiring bilateral sinus floor elevation will be recruited for a pilot study in split-mouth design. On both sides a lateral window will be prepared and the sinus mucosa will be elevated. After this step, the sides are assigned as test or control side. While the control side is just filled with augmentation material, an additional step is performed for the test side, i.e., prior to inserting the augmentation material, the cortical bone layer of the sinus floor is perforated several times into the trabecular bone layer to improve the blood supply to the grafting material. Thereafter, both sides are left to healing for 4-6 months until implant installation. At timepoint of implant installation, a bone biopsy will be collected to allow histological assessment of the grafted area.
Post-extraction implants are an alternative to traditional implant placement on completely healed bone, in order to reduce the number of surgical interventions, shorten treatment time, maintain bone architecture and thus provide better aesthetics. This study focuses on evaluating the results obtained by opting for different immediate placement of single dental implants protocols in a fresh alveolus, and its general objective is to compare implant stability and marginal bone loss (MBL) in implants installed post-extraction. For this, the investigators will placement Grand Morse Acqua or NeoPoros implants (Helix GM - Neodent, Curitiba, Brazil), in early loading protocols, with or without low level laser photobiomodulation (LLLT), in patients attending the Master of Oral Medicine, Oral Surgery and Implantology of the University of Santiago de Compostela for oral rehabilitation using osseointegrated single dental implants in the maxillary and/or mandibular region.
A multicenter prospective observational study aims to illustrate the clinical outcome of dental implants "Kontact MB" and the effects of its Mono Block design on the peri implant bone tissue recession and soft tissue conservation. 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 current research aims at evaluating the outcomes of the vestibular socket therapy in immediate implants using collagen plug, demineralized freeze-dried bone allograft, and deproteinized bovine bone minerals at both radiographic and clinical levels
This study will compare two techniques to achieve increase in ridge dimensions as a preparation for dental implants using a resorbable barrier membrane and bone particulate allogenic graft hydrated with saline or a growth factor called Recombinant Human Platelet-Derived Growth Factor (rhPDGF).
The aim is to comparatively evaluate the soft tissue volume changes that occur after tooth extraction and immediate dental implant placement using two different surgical techniques. These techniques are: the Socket-Shield technique and conventional immediate placement. The null hypothesis is that the Socket-Shield technique better maintains soft tissue volume after partial tooth extraction and immediate implant placement compared to the conventional technique. From a sample of 20 patients, they will be divided into groups of 10 and will be randomized using the random.org program. The soft tissue volume will be digitally recorded by intraoral scanning before tooth extraction and 6 months later. The soft tissue dimensional changes produced will be digitally evaluated and statistically analyzed.
After atraumatic tooth extraction and the assessment of the feasibility of immediate implant placement, patients will be randomly assigned to one of three treatment concepts: 1. Immediate Implant Placement and Immediate Provisionalization 2. Alveolar Ridge Preservation. After 4 months of healing an implant will be placed with simultaneous GBR and/or Soft Tissue Augmentation procedures, if needed. 3. Spontaneous Healing of the socket. After 4 months of healing, an implant will be placedwith simultaneous GBR and/or Soft Tissue Augmentation procedures, if needed. In all groups, four months after implant placement, a prosthesis will be delivered. From this experimental period onward, patients will be scheduled for maintenance. Clinical, radiographic and volumetric assessment will be performed by clinicians not involved in the surgery and blind with respect to treatment assignment at 1, 3 and 5 years post loading.
