Israeli prosthodontist, Michigan graduate student named William R. Laney Award recipients

Arlington Heights, Ill., March 13, 2021 – Zeev Ormianer, DMD prosthodontist from Tel Aviv, Israel, and Andrea Ravida, DDS, MS, graduate student in the Periodontics and Oral Medicine Department at the University of Michigan School of Dentistry in Ann Arbor, are recipients of the 2019 and 2020 William R. Laney Award, respectively. Named after AO’s first president and former editor of the International Journal of Oral and Maxillofacial Implants (JOMI), William R. Laney, DMD, MS, the award recognizes the best article published in the past year in the official publication of AO, in which Dr. Laney served for many years as Editor Emeritus.

While their research presentations are available in the on‐demand portion of “Game Changers,” the Academy’s 2021 Virtual Annual Meeting, recipients of the William R. Laney Award will be honored tomorrow during the Academy’s annual business meeting. Like several other awards, the Academy is recognizing individuals from both last year and this year due to the cancellation of its 2020 Annual Meeting.

Dr. Ormianer’s winning abstract is entitled, “The Effect of Moderately Controlled Type 2 Diabetes on Dental Implant Survival and Peri‐implant Bone Loss: A Long‐term Retrospective Study,” originally published in Volume 33, Issue 2, 2018. The aim of this study was to assess implant survival rates and long‐term bone loss around implants in a population of patients with moderately‐controlled T2DM, followed for a minimum period of 4.9 years.

According to Dr. Ormianer, Diabetes Mellitus (DM) is a metabolic disorder, a part of a group of metabolic diseases which influences the patient’s health status. A common complication that is associated with DM, especially DM type 2 (DMT2), is advanced periodontal disease. The prevalence of the periodontal disease is much higher in patients with DMT2 than people without the disease. In addition, the loss of periodontal attachment and alveolar bone starts in early stages of life in such patients compared to general population.

In conclusion, he states the results show that implant survival and bone loss levels were comparable to reported outcomes in the non‐diabetic population. The delayed insertion protocol presented less bone loss compared to other insertion methods. Likewise, less bone loss was found in implants placed in the posterior region. “I was surprised and honored when I was notified of the award. It all started when a friend and colleague, Dr. Jerry Kohen, asked me to review 20 years of data of implant dentistry,” recalls Dr. Ormianer.

“The first result of this collaboration was published in JOMI in 2010, which presented a three‐year follow up of immediate placed and restored maxillary implants. We noticed the number of Type 2 Diabetes patients that were restored and had long‐ term follow‐up data. There had been a lack of information in literature, so we collected the data for publication.”

“The Effect of Crown‐to‐Implant Ratio on the Clinical Outcomes of Dental Implants: A Systematic Review” published in Volume 34, Issue 5 September/October 2019 is the title of the winning JOMI abstract authored by 2020 recipient Andrea Ravida, DDS, MS.

The purpose of this study was to investigate the effect of C/I ratio (clinical and anatomical) on implant survival, marginal bone loss, and prosthetic complications. Systematic electronic and manual search was conducted to include clinical trials with a minimum follow‐up of 1 year. In total, 15 articles were included in the final analysis. Linear regression analysis did not reveal a significant correlation between anatomical C/I ratios and survival rate, marginal bone loss, or prosthetic complications. Similarly, no significant correlation was observed in the articles providing the clinical C/I ratios. In conclusion, increased C/I ratio does not seem to be directly related with increased marginal bone loss and does not represent a biomechanical risk factor for the stability of the prosthesis and for the survival of dental implants.

“I have always considered the William R. Laney Award one of the most prestigious scientific prizes in the field of implantology. As a young researcher and clinician, I am extremely happy and proud to be the 2021 recipient,” says Dr. Ravida. “This award gives me strength and motivation to keep studying controversial clinical topics and to help colleagues worldwide to practice evidence‐based dentistry. I want to thank the Academy of Osseointegration for this recognition and the coworkers of the study since without their hard work and support this work would not have been possible.”

Recipients of this annual award are selected by a group of peers who serve on the Academy’s William R. Laney Committee. Members of this committee reviewed dozens of abstracts when considering the winners.
