Eligibility

Age
18 Years to No maximum

Inclusion criteria

Inclusion criteria: Health patients; both genders; who presents loss of dental elements indicated for extractions due to root fractures, caries, endodontic lesions or periodontal disease, who remain totally edentulous at the end of the maxillary indications for rehabilitation with prostheses type protocol or overdenture; presence of adequate bone volume for indication of rehabilitation, confirmed by complementary exams; no systemic contraindications for intraoral surgical therapy; good oral hygiene; over 18 years old

Exclusion criteria

Exclusion criteria: Patients using medication that contraindicates the installation or changes the osseointegration of implants; presence of bone grafts in the planning area made previously that make it difficult to install implants; unfavorable bone conditions for implant placement in previous exams, bone availability for implants smaller than 8.5 mm or with predictable fenestrations in any bone wall that cannot be circumvented during surgery; pregnant or breastfeeding women and compulsive smokers more than 2 packs per day

Design outcomes

Primary

MeasureTime frame
The primary outcome tends to answer questions about comfort in implant placement using a guided technique, as well as the longevity of treatment with overdentures and protocols. In this study, this longevity lasted up to 1 year after the installation of the prostheses. It is expected from the technique that this outcome is in part favorable to guided surgery, since the lack of surgical opening generates less postoperative discomfort; however, different results regarding the longevity of the prostheses are not expected, as the scientific basis for longevity follows the standards described for prostheses performed using the conventional installation technique.

Secondary

MeasureTime frame
For secondary outcomes, radiographic and clinical analyzes will be performed, with evaluation of periodontal aspects, in addition to VAS analyses. It is expected that the techniques are close to each other but with superior radiographic and periodontal data for guided surgery, since this technique does not detach soft tissues for the installation of implants, and the literature describes the onset of initial bone resorption as a local circulatory problem in the alveolar crest mainly on extremely thin ridges, such as the anterior maxillary region. In addition, the visual analog scale analysis is expected to be quite favorable for guided surgery for the same reason, the non-performance of transsurgical incisions and sutures
