QUIROGA, Isabel et al. Comparison of the level of the bone crest in total edentulous rehabilitated with mandibular implants and removable prosthesis. Rev. Clin. Periodoncia Implantol. Rehabil. Oral [online]. 2018, vol.11, n.1, pp.28-31. ISSN 0719-0107.


The purpose of this research was to determine the pattern of reabsorption of bone tissue from rehabilitated implants with acrylic crowns that act as supports of a removable partial denture with extra-coronary retainers.

Material and method:

To measure this effect, a device was designed to standardize the measurement of the bone level by a retro-alveolar radiography with parallelism exposure technique, considering that this procedure allows to observe great amount of details, offering an image of high definition, with a minimum distortion, low cost and minimal risk of radiation.

The results: indicate that in a six-month interval measured after rehabilitation at 24 and 30 months respectively a bone resorption is observed, which on average reaches 0.12 mm, this difference being statistically significant between both recording times.


The resorption patterns of our research are similar to those that occur with other forms of rehabilitation on osseointegrated implants.
