Resumen
Introduction:
Following dental implant loading, marginal bone loss after one year must be evaluated to check correct maintenance of the bone levels.
Objectives:
To assess implant treatment success and quantify marginal bone loss 6 and 12 months after loading.
Material and method:
Sixty-one MIS® implants with a 1.8 mm machined neck were placed in 26 patients. Implant success was based on the criteria of Buser. Radiological controls were made 6 and 12 months after loading, measuring bone loss mesial and distal.
Results:
Twenty-two patients with 56 implants were included: 32 in the maxilla and 24 in the mandible. Two implants failed in two patients during the osseointegration phase (both in the maxilla), yielding an implant success rate of 96.4%. After 6 months, bone loss was 0.80±1.04 mm mesial and 0.73±1.08 mm distal, while after 12 months bone loss was 0.92±1.02 mesial and 0.87±1.01 distal.
Conclusions:
Bone loss 6 and 12 months after machined neck implant placement was within the normal ranges described in the literature.
