Summary

The objective of this clinical trial is to evaluate the impact of different torque values applied during transmucosal abutment placement in dental implants on marginal bone loss and peri-implant parameters, including the patient's perception of the treatment.

The main questions the study aims to answer are:

1. Is there any difference in marginal bone loss between abutments torqued at 15 Ncm, 30 Ncm, and submerged implants without immediate transmucosal connection?
2. Are there differences in microleakage between the different torque levels?
3. How do these torque values affect peri-implant soft tissues and patient satisfaction?
4. Does the applied torque influence the patient's quality of life after the prosthetic phase?

Each participant will receive three dental implants during the same surgical procedure. One of the following approaches will be applied to each implant:

1. A transmucosal abutment torqued to 15 Ncm
2. A transmucosal abutment torqued to 30 Ncm
3. A healing cap without transmucosal connection (submerged implant)

After implant placement, clinical and radiographic assessments will be performed to measure marginal bone loss and peri-implant parameters.

Conditions

  • Soft Tissues According to the Abutment Torque
  • Microleakage Accordint to the Abutment Torque
  • PROMS According to the Abutment Torque
  • Marginal Bone Loss According to the Abutment Torque

Interventions

PROCEDURE

Abutment torqued to 15 Ncm

A dental implant surgery will be performed in which three implants will be placed. On one of them, a 2 mm slim abutment will be connected with a torque of 15 Ncm; on another, the same abutment will be connected with a torque of 30 Ncm; and on the third, a 2 mm healing cap will be placed and the implant will be left submerged for a subsequent second-stage surgery.

PROCEDURE

Pilar torqued to 30 Ncm

A dental implant surgery will be performed in which three implants will be placed. On one of them, a 2 mm slim abutment will be connected with a torque of 15 Ncm; on another, the same abutment will be connected with a torque of 30 Ncm; and on the third, a 2 mm healing cap will be placed and the implant will be left submerged for a subsequent second-stage surgery.

PROCEDURE

2 mm healing cap

A dental implant surgery will be performed in which three implants will be placed. On one of them, a 2 mm slim abutment will be connected with a torque of 15 Ncm; on another, the same abutment will be connected with a torque of 30 Ncm; and on the third, a 2 mm healing cap will be placed and the implant will be left submerged for a subsequent second-stage surgery.
