Brief Summary
This study consists in a double-blinded randomized controlled trial which objective is to assess the effect of the implant-abutment connection type -external hexagon, internal hexagon and conical connection- in the periimplant marginal bone loss in vertical side and the bacterial leakage 12 months after prosthesis placement.

Interventions
Antibiotic prophylaxis will be done. After rinsing with 0.12 % chlorhexidine, patients will receive local anaesthesia. A crestal incision will be done and a mucoperiostic flap will be raised. As the commercial specifies, progressive diameter drills will be used under constant sterile saline irrigation to prepare the implant site. Once finished the drilling sequence, one investigator will open the opaque envelope to know which type of implant, depending on the connection, has to be placed by the surgeon. Dental implant will be placed crestally and depending if it has primary stability or not, it will be leaded submerged or non-submerged. The flap will be repositioned and sutured without tension with 4/0 polyamide. Postoperative instructions and medication will be prescribed and explained.
Eligibility Criteria
You may qualify if:
- Subjects who accept signing voluntarily the informed consent before doing any action related to the study.
- ≥18-years-old patients.
- Edentulous single spaces or edentulous posterior maxilla or mandible (from the first premolar to the second molar) with screw-retained single fixed crowns.
- Single implants successfully osseointegrated placed at least 16 weeks post-extraction.
- O'Leary plaque index and or bleeding on probing ≤25%.
- Dental implants with screwed-retained prosthesis.
You may not qualify if:
- Systemic diseases that can interfere dental implant placement.
- Any contraindication for surgery procedures.
- Heavy smokers (\> 20cig/day).
- Background of drug abuse or other factors such as psychiatric diseases that, in opinion of the examiner, could interfere with the ability of the patient to cooperate and compliment with the study.
- Patients who have had participated with another clinical trial the last 30 days.
- Pregnant women or in lactation.
- Patients with bad oral hygiene or not motivated.
- Probing pockets depths with bleeding of ≥4 mm on a tooth adjacent to the edentulous space.
- Guided bone regeneration required in the same time of the implant placement.
