Filter by:Implant retained overdentures are a cost-effective treatment for elderly patients suffering from complete tooth loss. Despite the high success rate of implants in the general population, older adults lacking all teeth are a challenging population for implant therapy, often presenting limited bone disponibility, narrow alveolar ridges, diminished bone density, scarce inserted gingiva and several co-morbidities.Thus, improving their possibility of success in implant therapy avoiding further surgical interventions is key. Platelet-rich fibrin (PRF) is a blood derivate that can be easily and economically obtained from patients and that has shown promise of reducing the complications and improving the success of implant therapy, nevertheless its benefits in patients receiving implant retained overdentures has not been stablished. It is possible that PRF can improve the results and diminish the complications of implant therapy in older adults. The investigation aims to demonstrate that the use of platelet-rich fibirn (PRF) is safe and beneficial for implant treatment in older adults suffering from complete tooth loss.
To evaluate in a comparative way the patient's perception in implant surgery in the posterior mandibular quadrants depending on whether the operation is performed under trunk anaesthesia or infiltrative anaesthesia, in both cases with Articaine. Randomized and multicenter prospective study to be developed in eight centers with similar socio-professional characteristics, with the same operative protocol. A significant sample of patients will be randomized to undergo the same intervention (surgery to place implants in the posterior mandible) under one or another type of anesthesia (inferior alveolar block nerve or infiltrative) and data will be collected using a Numerical Rate scale on four occasions (after the incision, after drilling, after suturing and after 12h).
This will be a prospective, randomized multicenter study to determine the safety and efficacy of the T3 Certain Tapered with DCD as compared to T3 Certain Tapered without DCD. All implants will be placed in the maxilla or mandible in a single stage manner and loaded with prosthesis after 6 weeks of healing. Final restorations will take place no later than 4 months following implant placement surgery. The implants will be evaluated yearly for 2 years.
GM Zygomatic implant is intended to be surgically placed in the posterior region of the maxilla and zygoma. It is indicated for multiple prostheses in case of severe resorption in the maxilla and total edentulism (situations in which the installation of convectional implants is contraindicated). The objective of the study is to confirm the long-term safety and clinical performance of GM Zygomatic implants and GM Zygomatic abutments in daily dental practice setting, by means of a prospective collection of clinical data concerning the success and survival rates of these devices. Devices will be used according to standard routine in daily practice, according to all indications as specified by the manufacturer in the instructions for use (IFU). Ten patients will be followed for 36 months and monitored for Adverse Events by the Investigators until the last protocol-related procedure of a patient is completed.
Purpose: Evaluation of patients' satisfaction, biting force measurement and radiographic evaluation of abutment teeth of tooth implant supported bridge, unilateral attachment and conventional partial denture in mandibular distal extension cases. Materials and methods: Twenty four patients were selected and divided into three equal groups, each of eight patients: patients of group I Patients received a fixed tooth implant supported bridge, patients of group II Patients received a removable unilateral attachment partial denture and group III Patients received a conventional removable partial denture.Evaluation included patient satisfaction and biting force measurement radiographic evaluation of terminal abutments.
The study population comprises 20 completely edentulous patients aged 60 years and older with severe mandible resorption. Each patient receives two inter-foraminal implants (Neoss Ltd., Harrogate, UK). Following randomization, implants are loaded either immediately after dental implant surgery or three months after implant placement with the Locator®-abutment system. At follow-up visits 3, 6 12, 24 and 36 months after loading, implant stability is evaluated with Periotest® and Ostell®.
To compare a flapless technique of alveolar ridge preservation to a flap technique to determine if preserving the periosteal blood supply would prevent loss of crestal ridge width and height.
This clinical study will evaluate the safety and performance of the T3 short dental implant when placed in the posterior maxilla and mandible.
This will be a prospective, randomized, observational study. All implants will be placed in either the maxilla or mandible and loaded within 2 months with a provisional or definitive prosthesis. The implants will be evaluated yearly for 2 years.
The aim of this study is to prospectively collect clinical data to confirm the safety and clinical performance of Neodent Titanium Base Abutment and Pro PEEK Abutment in daily dental practice setting, by means of a randomized clinical study of prosthetic rehabilitation using these devices. A total of 48 healed implant sites (at least 4 months post-extraction) shall be included during the sample enrollment (24 patients), which will be randomly divided into two groups, so that each patient receives one implant from each group (removal and non-removal of the abutment placed at the time of surgery). Patients will be followed for 24 months after implant loading. It is expected that there is no difference in peri-implant bone level change between the two treatment groups.
