An Introduction to Bioactivity via Restorative Dental Materials
Published in Mary Anne S. Melo, Designing Bioactive Polymeric Materials for Restorative Dentistry, 2020
Mary Anne S. Melo, Ashley Reid, Abdulrahman A. Balhaddad
Another area of concentrated investigation in prosthodontics is the antibacterial polymeric denture materials. The high rates of adhesion of oral microorganisms to denture base materials tremendously impact oral health with many infections associated with the use of dentures such as oral stomatitis, candidiasis, and dental caries in teeth-supported dentures (Yitzhaki et al. 2018). Acrylic polymethyl methacrylate resin (PMMA) is considered one of the most commonly used materials as a denture base (Garcia et al. 2020). Unfortunately, PMMA is highly susceptible to microbial adhesion and infiltration (Buergers et al. 2007).
The Excessive Gagging Reflex
Published in Eli Ilana, Oral Psychophysiology, 2020
One possible explanation of the development of an excessive gagging reflex in dental patients might be the presence of dental anxiety in those with a specific personality set-up, which prevents the patient from admitting it even to him/herself. In such cases, gagging serves as an efficient way to avoid treatment. The concomitant deterioration in dental health brings many of these patients to require prosthodontic appliances, causing further adaptation problems.
Implant-tooth fixed supported prosthesis: A review

For decades, dental implants have been recommended to improve the retention of removable dental prostheses (RDPs) placed in edentulous mandible (Rammelsberg et al. 2013). Moreover, prosthodontic options include fixed dental prosthesis (FDPs) on either, abutment teeth or abutment implants, a combination of abutment teeth and implants, implant-supported single crowns and resin-bonded prosthesis.

The risk of bias assessment of the included studies is summarized in Supplemental Table S3. Overall, RCTs did not properly conceal group allocation, and neither patients nor investigators were blinded to treatment assignment, intervention and outcome assessment. On the other hand, non-RCTs displayed low risk of bias. While the included cohort studies generally exhibited low risk of bias, about 70% did not identify confounding variables nor adjusted for them in their analysis. Finally, randomization and sample size calculation were mainly lacking in animal studies attributing to the high risk of bias. Years of publication varied extremely across research areas. For instance, all studies on head and neck cancer were fairly recent and published between 2009 and 2021. In contrast, studies in prosthodontic treatments and local anesthesia were published between 1982 and 1992. Also, orthodontic forces and tooth movement animal studies were conducted between 1998 and 2002. Figure 2 illustrates the best time for different interventions reported in the included studies.
Radiographic peri-implant bone loss after a function time up to 15 years
Published in Acta Odontologica Scandinavica, 2022

This is a cross-sectional clinical and radiological study in combination with data collected retrospectively for baseline variables. All patients referred to the Specialist Clinic of Periodontology and Oral Prosthetics (Public Dental Service at Skanstull, Stockholm) where implant therapy was performed during the period 1999–2005 were included in the study group. Dental implant surgical procedures were performed by periodontists, whereas prosthodontists or general dentists performed implant prosthetic treatment. In total, 263 patients were invited to a clinical examination and 163 patients attended (62%) with a total of 470 implants (Figure 1). Sixty patients declined examination and 40 patients failed the appointment. The patients were invited by mail for a free of charge clinical and radiographic examination.
The influence of framework material on stress distribution in maxillary complete-arch fixed prostheses supported by four dental implants: a three-dimensional finite element analysis
Published in Computer Methods in Biomechanics and Biomedical Engineering, 2021

In their short-term follow-up study, Malo et al. (2018) suggested the use of PEEK materials for full-arch implant-supported restorations based on outcomes for prosthetic survival, dental implant survival, marginal bone loss, complications, and subjective patient evaluation. Although a clinical study by Malo et al. (2018) reported a low incidence of mechanical complications for All-on-4 prostheses constructed with PEEK frameworks, the study’s one-year follow-up period is insufficient for drawing reliable conclusions in the long-term biomechanical behavior of these framework materials. Considering the present results of PEKK and PEEK materials that revealed higher transference of stresses to prosthetic components as compared to zirconia and titanium frameworks, clinicians should be aware of the possibility of screw loosening and screw fracture when using PEKK or PEEK for all-on-four frameworks. Long-term clinical follow-up studies are needed to evaluate the performance of these materials in routine prosthodontic applications.
