Our office has been in the forefront of implant placement in Spokane since 1987. A database was kept from 1987-present. Overall a 97.3% success rate was obtained. An abstract of our study can be found below. A complete copy of our study can bedownloaded by selecting our study.And we have continued to maintain our database. Overall, our office has placed over 5,000 implants with the same success rate.
ABSTRACT:
Implant dentistry has evolved and matured since the early days of P.I. Branemark. New technologies, materials and techniques have made treatment options utilizing implants the new standard of care. In this study we have amassed a sizable amount of data on 1,750 consecutively placed implants in a private practice setting and evaluated them based on seven parameters. 1) Overall success rate: A total of 40 failures were observed out of a total of 1,492 implants, for an overall success rate of 97.3%. 2) Effect of location within the mouth: The range of success varied between 95.54% – 98.58% based on location. There is no significant difference in success rate based upon location in the mouth. 3) Effect of implant surface texture on success: The success rate for HA coated implants was slightly greater than machined surfaces 97.86% and 96.08%, respectfully. Other roughened surfaces, such as sand blasted, acid etched, and TPS also showed a higher success rate at 98.32%. 4) Effect of implant length on success: There was a definite correlation between increased length and increased success rate. The longest implants (16mm) showed a 1% failure rate, 13mm implants showed 3.27% failure, 10mm implants showed 3.30% failure and 7 and 8mm implants showed a higher 5.56% failure rate. 5) Effect of timing of surgery on success: There is a slightly higher success rate with immediate implants when compared with delayed implant placement. Immediate implant placement is highly successful in the premolar and anterior regions, but not practical or predictable in the molar regions. 6) Effect of bone grafting on success: Only 5 failures out of 225 implants were observed in grafted sites, indicating no difference in implant survival rates of implants placed into grafted bone or into naturally adequate bone sites; and 7) Effect of implant type on success: Based upon the data in this study, the ScrewVent implant had the highest success rate (98.53%), followed by SteriOss Replace (97.32%), CoreVent (92.38%), and finally the MicroVent implant (89.93%).
Dr. David has a wonderful chairside manner, just as his father did when I saw him many years ago. He made me feel very comfortable.

I would highly recommend Dr. Engen and his office staff to anyone whose child was apprehensive about having braces. Other than the high level of professionalism, I appreciate the down-play of cutsie-pie gimmicks for kids. He thoroughly explained everything to us right from the start.

Because of the internet information provided about his background and education, I feel I have a top level, up-to-date professional taking care of me.

State of the art care! I like the “get it right” attitude. After eight years I have not had one negative experience.

Dr. Engen was great! He explained my diagnosis and the procedure required thoroughly. I was even asked if I liked the colors of paint for the office.
