Abstract :Background: The insertion of dental implants involves the drilling process. This drilling process should be as conservative as possible to avoid damage the bone. When this drilling is conservative and no irrigation was used we can obtain bone particles that can be used as a particulate bone graft. The objective of this study is to evaluate the efficiency of a biological low-speed (without irrigation) drilling and to analyze the bone obtained in order to know the viability and vitality of the bone cells contained in this bone.
Findings: In this pilot study were collected samples of biological drilling (low revs without irrigation) and standard drilling protocol in two patients undergoing implant surgery. The samples shall be analyzed by conventional histology and cultivated in order to observe cell growth. The samples of bone obtained by biological drilling shows living cells in the conventional optical microscopy and cell growth when it is cultivated. The bone obtained with drilling at high revolutions shows no living cells and when to be cultivated not obtained cell growth. Moreover, the preservation of bone particles of biological drilling was more effective to support the cell survival more than physiological saline.
Conclusions: The biological drilling at low revs gives us the possibility of collect bone grafts in a simple manner. This collection of bone allows us the treatment of areas in the same surgical phase that would require bone grafts. Bone Presevation in Endoret (PRGF) is more effective than physiological saline in supporting cell survival.
