Peri-implant Tissues in BLX® Implants

Behavior of Peri-implant Tissues in BLX® Implants Placed on Mature Scarred Bone

This is a randomized triple-blind clinical trial to evaluate the behavior of peri-implant tissues (bone and soft tissues) in BLX implants loaded early or delayed and with different surgical milling protocols. To this end, 40 BLX implants with a diameter of 3.75x10 will be placed in areas of mature bone scarred after extraction. They will be divided into 2 study groups, and these in turn into two subgroups. Group A: complete milling, Group B: partial milling. Each group will be assigned with code 1: early load and code 2: deferred load. Clinical and radiological parameters will be evaluated.

Inclusion Criteria:

• Patients without systemic pathology
• Adult of age who agree to be part of the study and sign the informed consent.
• Patients smoking less than 5 cigarettes / day,
• Patients not being completely edentulous
• Unitary / multiple absences in the area posterior with or without free ends to distal, maxillary or mandibular that do not require regenerative techniques
• Area of mature bone healed at least 6 months post-extraction.
• The minimum torque for early loading will be 25 N. The placement of the implant will be mechanical up to 40 N maximum and manually finished with a surgical dynamometer.
• The placement of the abutment will be at a minimum of 25 N, in case the primary stability of the implant allows it, it will be placed at 35 N.
• The placement of the implant must always be 4 mm below the future gingival margi

Exclusion Criteria:

• Immunosuppressed patients
• Aesthetic edentulous areas of 13-23 and 33-43
• Smokers of more than 5 cigarettes
• Implants with a lower torque whose will be submerged with a screw and a protocol will be followed in 2 phases, being discarded from the study.
• Index of bleeding greater than 30%
• Patients with less than 2 mm of keratinized gingiva
• Implants with ISQ index <55
• When a margin of 1 mm safety cannot be assumed to the inferior dental nerve
