Abstract:
To investigate the early outcome of a dental implant with bioactive Calcium-phosphate (CaP)
coating in the first 6 week of usage in mandibular clinical situations, for determenatin if it is possible
early prosthetic loading by measurements with Osstell and resonance frequency analysis (RFA), and
bone density. Materials and methods: Study of the 6 weeks function of 16 oral implants in 6 patients,
in the mandibular clinical situations we have evaluated the clinical and paraclinical parameters to predict implant outcomes.We initiated a short- term prospective study on Bioactive Alfa Gate
implants. The following para clinical analyses were determined to access the necessary dates for
success and survive rate of implants: The implant primary and changed stability of 6 weeks stability
(the resonance frequency analysis (Osstells Mentor® (RFA) Osstell AB, Gothenburg, Sweden) which
was done weekly and the result was registered to make the statistical comparison. All surgeries were
performed under local anaesthesia with 3 patient with open flap and 3 with flapless access to the
bone. Osteotomy preparations of neo alveolas were performed with low speed high-torque drill units
using intense irrigation with a cold saline solution. During each site preparation of the neo alveolas
for the implants, the bone quality II to III was recorded. All implants were placed manually and final
torque was measured with a manual torque control wrench with result of 35-45 Ncm. And each
implant was covered with healing abutment for easy access for the quantitative evaluation of implant
stability, RFA was recorded with the Osstell Mentor device. Orthopantomographic X-ray images
were used for calculation of radiological bone loss and the respective success criterion Results: The
ISQ testing for signs of initial and changed stability of 6 weeks after implantation could show notable
result. The ISQ values of the stability could be estimated for the implants at the time of healing
abutment placement. Statistically results demonstrate that implants present a better stability after 6
weeks post insertion. The ISQ mean values for the 16 implants prosthetic rehabilitated after 6 week of
healing period were 70.75 comparing with 67.63 mean ISQ value after implant placement, the lowest
ISQ mean values was 64.63 wich was registered in week 1 after the implantation. From week 2 till
week 6 was in a continue increase in ISQ values. Panoramic radiographs based on the twodimensional availability, While looking at the peri-implantary loss of bone the wasn’t observed
Conclusion: The clinical and para-clinical outcomes in this study indicate a high stability value after 6
weeks, and we had the possibility of prosthetic treatment after the studied time.
