Eligibility
Inclusion criteria
Inclusion criteria: To participate in this study, patients must present the following characteristics: Similar degree of atrophy in the bilateral posterior region of mandible, with a minimum residual bone height of 10 mm and width of 6.0 mm, distance from the bone crest to the superior cortex of the canal mandibular (evaluated by Cone Beam computed tomography); Additionally, for eligibility, patients must be 18 years of age, must sign a consent form prior to beginning the study and be committed to participating throughout the study period follow-up
Exclusion criteria
Exclusion criteria: To participate in this study, patients must not present the following characteristics: general contraindications to surgeries with dental implants; patient undergoing irradiation in the head and neck region; patients with immunosuppression and immunosuppression; treated or in treatment with anti-resorptive medications or those that alter bone metabolism; untreated periodontitis; poor oral hygiene and low motivation; pregnancy or breastfeeding; uncontrolled diabetes; psychiatric problems or unrealistic expectations; absence of dentition opposite the area intended for receive the implants; extraction sites (less than 3 months post-extraction); smokers
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Compare the clinical result of extra-short implants installed in the posterior area of ??the mandible with that of conventional implants through analysis of the success and survival rate (implant and prosthesis). The following clinical parameters will be evaluated after 3,6, 9, 12, and 24, 36 and 48 months: Bleeding on probing (presence or absence), Mobility (presence or absence), Suppuration (presence or absence), Probing depth, Marginal mucosa level, Clinical insertion level and Plaque index. A manual periodontal probe will be used (William's Probe; Hu-Friedy®, Chicago, IL, USA). All measurements must be taken by a calibrated examiner | — |
Secondary
| Measure | Time frame |
|---|---|
| Analysis of implants over time,comparing between groups:Marginal bone loss, through radiographic analysis, where periapical digital radiographs will be taken on day “0” (zero), at the time of surgery and after 3, 6, 9, 12, 24, 36 and 48 months after surgery. Insertion torque and Resonance Frequency Analysis (RFA): A manual torque wrench will be used to determine the insertion torque of each implant. Mean and standard deviation will be calculated and statistical t-test will be applied. Immediately after implant insertion, the implant stability coefficient (ISQ) will be measured using RFA, with the Osstell instrument (Integration Diagnostics AB, Goteborg, Sweden). Measurements will be carried out in the buccal and lingual regions. The values ??obtained will be noted on a spreadsheet with patient identification, implant dimensions, installation region, and date of measurement of ISQ values, which will be obtained at the time of surgery,3, 6, 9, 12, 24, 36 and 48 months | — |
