This study will compare patient-reported outcomes, as well as the type and incidence of complications, and bone marginal loss after 12 months in implants installed using the transcrestal approach (tSFE) with an osseodensification system (performed according to the protocol by Huwais et al. 2018), or installed simultaneously using the lateral window technique (lSFE) with sinus lift. A blind, randomized, controlled clinical trial will be carried out with individuals over 18 years old, and with single tooth loss in the posterior maxilla, where the residual bone height (RBH) is 3 to 5 mm. The tSFE will be performed with osseodensification burs (Densa Bur, Versah, USA) using a counterclockwise motion, associated to synthetic biomaterial (hydroxyapatite and beta-tricalcium phosphate). The lSFE technique will require the sinus to be filled with the same biomaterial as the group using the other technique, and the antrostomy to be covered with a polydioxanone-based membrane. The patient's post-operatory perceptions will be evaluated by self-administered questionnaires quantifying social and professional isolation, physical appearance, duration and changes in quality of life, eating and speech, diet variations, and sleep deficiency for 2 weeks after the procedure. Pain will be assessed with the visual analogue scale (VAS). Immediately after prosthetic rehabilitation, cone beam tomography will be performed. Controls at 6 and 12 months will be performed. In these images, the marginal bone level in relation to a fixed reference point on the implants (upper part of the platform) will be measured mesially and distally in each implant, using a specific program (ImageJ - version 1.49v / NIH software - Bethesda, MD, USA). Generalized estimating equations will be used to compare the two treatments overtime. The significance level used will be 0.05.

| Lateral window | Procedure | A full-thickness mucoperiosteal flap will be elevated. The lateral window will be made with a spherical diamond drill (number 8) at 20,000 rpm. The mesiodistal and apicocoronal dimensions of the lateral access window to the sinus will be measured in all the participants using a caliper. Sinus membrane elevation will be performed with manual instruments. |
