Abstract
Tooth loss is an ongoing problem where functional as well as aesthetic impairments are involved. In order to restore the aesthetic view and the chewing functionality, different teeth replacement modalities can be employed, including fixed dental prostheses, removeable dental prostheses, and dental implants. The choice of a particular dental treatment is influenced by a variety of clinical, personal, and social factors.
A pilot study was conducted to highlight and resolve any potential issues that would have arisen in the main study. This decision had great benefits in terms of defining clear inclusion and exclusion criteria. For example, the factor of dentists’ experience was not investigated in the main study due to patients’ cultural reservations regarding critique of their dentists. New parameters for inspection in the main study were identified to manage possible confounding.
Data was collected from a range of dental clinics across three governorates in Iraq with the use of medical records, interviews and questionnaires. The study subjects included 328 candidates for teeth replacement, 2964 dental implant users, 432 dental patients, 212 cases of dental implants installed during the COVID-19 pandemic, 276 cases of dental implants installed in patients with Bruxism, and 38 specialist dentists. Identifying the factors that could dictate the outcome of dental implants would be vital in minimising failure. Investigated factors fell under one of two categories: static factors including age, gender and site of implant unit, and dynamic factors including type of protheses, implant material and type of insertion procedure. Three types of failure were recognized: mechanical, biological, and a combined bio-mechanical failure. Fracture-associated failure was seen in over 72% of the overall failure rate. The great impacts the COVID-19 pandemic had on patient interactions with dental care and on the outcome of dental implants were investigated. Themes like appointment cancellations, treatment plan amendments, remote consultations and factors incentivising dental treatment recommencement were explored. The success rate of dental implant units was 12.6% lower than the rate documented for pre- pandemic cases. A link between COVID-19 and the biological aspects of dental implant outcomes was highlighted in the increased failure rate among infected individuals and in the increased proportion of biomechanical failure after the pandemic.
This study also aimed to investigate the outcome of dental implants in users with Bruxism, a parafunctional activity that entails involuntary clenching and grinding of the teeth. The recorded failure rate among Bruxism users was ca. 3.3 fold higher than that seen in dental implant users with no Bruxism.
The field of dental implant is very dynamic. Thus, regular reviewing of the literature is vital as it helps to identify new dental materials, insertion protocols, and designs that could combat current issues.
