Description
Inclusion Criteria:
- Patients with sufficient bone volume availability apically and palatally that allows the correct positioning of the implants (Kan et al, 2011);
- Implants with primary stability of 20-45 N (Gallucci et al, 2014);
- Patients with teeth to be extracted in the Class I, II or III corono-radicular position, according to Kan et al. (2011);
- Patients with distance from the bone crest to the point of contact in adjacent teeth less than or equal to 6.5mm (Buser et al 2017).
Exclusion Criteria:
- Presence of diabetes, blood disorders and systemic diseases that prevent the surgical procedure;
- History of radiotherapy in the head or neck region;
- History of treatment with bisphosphonates;
- Pregnant or lactating women;
- Patients with teeth to be extracted in the Class V corono-radicular position, according to Kan et al. (2011);
- Gingival recession in the teeth indicated for exodontia (Kan et al, 2001);
- Acute infection at the implant site (Morton et al, 2014);
- Unavailability to attend the FOP / UNICAMP on the pre-determined days.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: Guided surgery (GS)
Installation of dental implant with the aid of the virtually planned guide by means of specific software
|
A minimally traumatic extraction will be performed aiming at the preservation of tissue integrity. After this step, milling will be performed using a sequence of guides and cutters recommended by the Raptor Implacil / Bioparts (Implacil De Bortoli) system manufacturer for implant installation (Cone Morse 3.5mm from 11-13mm Implacil De Bortoli) in computer-guided surgeries. In the spaces between the implant and the buccal bone plate will be filled with xenogene biomaterial (Geistlich Bio-Oss 0.25-1mm). Immediately after implant installation, the prosthetic component (Smart Line, Trunnion CM 3.5mm - T 1.5-3.5mm, height 4mm - Implacil De Bortoli) will be placed. If necessary, the sutures of the surgical procedures will be performed with polygalactin 5.0 (Vycril Rapid®, Jonhson's Jonhson, São José dos Campos) and will be removed after 7 days. |
Active Comparator: Conventional surgery (CS)
Installation of dental implant performed freehand using a conventional surgical guide made by study models
|
The sequence of cutters recommended by the manufacturer for this type of surgery and installation of the same type of implant (Cone Morse due cone 3.5mm) will be adopted.
The perforations of the collar for future insertion of the implants will be performed aiming the installation of the implants with its platform installed with sub-crestal position.
The implant should be installed along the palatine wall to obtain primary stability, at the center of the mesio-distal width predetermined by the final restoration, with a minimum distance of 2 mm from the adjacent tooth, and 3 mm from the free gingival margin, becoming slightly palatinate (Kan et al, 2018).
Immediately after installation, the prosthetic component (Smart Line, Trunnion CM 3.5mm - T 1.5-3.5mm,
height 4mm) will be placed.
If necessary, the sutures of the surgical procedures will be performed with polygalactin 5.0 (Vycril Rapid®, Jonhson's Jonhson, São José dos Campos) and will be removed after 7 days.
