Brief Summary:
The main objective of this study is to evaluate the efficacy of an acellular dermal matrix membrane to increase the peri-implant soft tissue thickness and to reduce marginal bone loss during non-submerged implant placement, as compared with the standard protocol for implant placement. The test hypothesis is that placing an acellular dermal matrix membrane simultaneous to implant placement in the posterior mandible, will increase the soft tissue thickness and consequently reduce the marginal bone level changes.
The study is designed as a doubled-blind, parallel groups, randomized clinical trial with a 1-year follow-up
Detailed Description:
The study is designed as a doubled-blind, parallel groups, randomized clinical trial with a 1-year follow-up. The randomization sequence will be created using a computer-generated list by an independent researcher. Allocation concealment will be kept by means of opaque sealed envelopes that will be open by one of the researchers during surgery, and revealed to the operator immediately after implant insertion.
All patients will receive standardized oral hygiene instructions consisting on the use of a manual or power-driven toothbrush and specific interdental brushes. Then, patients will be randomized to one of the following groups:
* Test Group :Mucoperiosteal flaps will be raised and the conventional drilling sequence for implants will be implemented (Camlog Conelog Screw-Line Promote Plus implants). Implants will be placed 1 mm below the bone crest. The diameter of the implant will be in the range of 3.8 and 4.3 mm. Consecutively, 4 to 6 mm height healing abutments and the allogenic membrane (NovoMatrix®, BioHorizon) folded in two on top of the implant (secured with the healing abutment), will be placed. Finally, flaps will be sutured with 6/0 polypropylene monofilament. Patients will be instructed to rinse with 15 ml of 0.12% chlorhexidine (Perio-Aid tratamiento, Dentaid SL, Barcelona, Spain) 60 seconds twice per day until suture removal, that will take place 14 days later. Anti-inflammatory drugs will also be prescribed (Ibuprofen 600 mg every 8 hours upon patient´s needs)
* Control Group: All the procedures will be the same as in the Test Group, with the only difference that no attempt to thicken the mucosa with the acellular dermal matrix will be performed.
