Loss of teeth due to accident, extraction or localized periodontal diseases
Conditions
Interventions
A group of 42 patients using mandibular complete dentures that reported difficulty using the full dentures were rehabilitated with 2 narrow-diameter implants (2.9x10mm, Facility Implant, Neodent) in t

Eligibility
Age
60 Years to 90 Years
Inclusion criteria
Inclusion criteria: New complete dentures in usage for at least 3 months; Difficulty in adapting to the use of the lower prosthesis due to the lack of retention and stability; Clinical and imagological signs consistent with atrophic edentulous mandible; No self-reported systemic health problems; Do not use any medication in the last 3 months that affects the immune response; Adequate bone quality and availability without the need for local bone graft.
Exclusion criteria
Exclusion criteria: Patients with any of the following characteristicst: local and systemic clinical impossibility for surgical treatment with dental implants such as the presence of intraosseous lesions and infections, uncontrolled diabetes, uncontrolled hypertension and cardiac problems. Patients with a history of chemo/radiotherapy in the last 10 years or who use systemic medications that may interfere with bone repair (eg, bisphosphonates); Patients who do not have time available for care in educational institutions.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Evaluate the masticatory function before the intervention, and after the installation of the implants in the following period of time: 30, 90, 180, 360 days and in the scheduled follow-ups of 2, 3, 4 and 5 years. | — |
Secondary
| Measure | Time frame |
|---|---|
| Evaluate the primary and secondary stability of the implants by analyzing the resonance frequency in the following intervals: baseline (T0 - installation), 7, 15, 30, 60, 90, 180, 360 days and in the scheduled follow-ups of 2, 3, 4 and 5 years.;Monitor the implant osseointegration process and peri-implant health through peri-implant clinical examination and collection of peri-implant fluid at 7 days, 15, 30,60, 90, 180, 360 days, and in the scheduled follow-ups of 2, 3, 4 and 5 years.;Quality of life, Degree of Patient Satisfaction, Impact on Daily Life and Self-perception of Oral Health before and after the installation of mandibular overdentures applying annually validated questionnaires for 5 years.;Monitor and evaluate the marginal bone loss and the posterior reabsorption of the mandibular ridge at 0 (baseline), 1, 2, 3, 4 and 5 years after mandibular overdentures loading using panoramic radiographs.;Monitor and evaluate the resorption of the anterior and posterior maxillary ridge at 0 (baseline), 1, 2, 3, 4 and 5 years after mandibular overdentures loading using panoramic radiographs.;Monitor and evaluate the circumferential bone loss of the implants and the posterior bone resorption at 1, 3 and 5 years after mandibular overdentures loading using cone-beam computed tomography.;Survey of the types and frequency of prosthetic complications through the analysis of the records made in the annual periodic follow-ups after mandibular overdentures loading. ;Estimation of implant success and survival rates evaluated using the clinical criteria proposed by Misch et al. (2008). Success refers to implants without pain or sensitivity to function, no mobility and marginal bone loss <2 mm, and with no history of exudates. Survival is assessed as a remnant in situ that is in its position of installation, at the moment of consultation, regardless of the condition of the other components/tissues related to it (bone, soft tissue, prosthetic abutment). screw, prosthetic crown, | — |
