This paper provides an overview on the use of virtual surgical planning (VSP) and point-of-care 3D printing (POC 3DP) in oral and cranio-maxillofacial (CMF) surgery based on a literature review. The authors searched PubMed, Web of Science, and Embase to find papers published between January 2015 and February 2022 in English, which describe human applications of POC 3DP in CMF surgery, resulting in 63 articles being included. The main review findings were as follows: most used clinical applications were anatomical models and cutting guides; production took place in-house or as “in-house—outsourced” workflows; the surgeon alone was involved in POC 3DP in 36 papers; the use of free versus paid planning software was balanced (50.72% vs. 49.27%); average planning time was 4.44 h; overall operating time decreased and outcomes were favorable, though evidence-based studies were limited; and finally, the heterogenous cost reports made a comprehensive financial analysis difficult. Overall, the development of in-house 3D printed devices supports CMF surgery, and encouraging results indicate that the technology has matured considerably.

Assessing bone density in prospective dental implant sites is crucial both for choosing the implant type and for planning a drilling procedure that will ensure the implant’s primary stability and osseointegration. This study aimed to investigate possible differences between the bone densities of various edentulous sites in the maxilla and mandible. The study was conducted on a group of forty partly edentulous patients who underwent radiological examination by scanning the areas of interest using cone beam computed tomography (CBCT). Hounsfield units (HU) were analyzed using dedicated software. Higher HU were observed at the site of mandibular central incisors compared to the site of maxillary central incisors. The HU values in the mandibular first molars region were higher than those of the maxillary first molars. Buccal vs. lingual or palatal cortical HU values did not differ significantly. Within the limitations of this study, it can be stated that an objective assessment of site-specific bone density before the installation of dental implants may provide valuable clinical information for the selection of implant size and the planning of a patient-specific drilling protocol.

Introduction : To establish the skeletal pattern in subjects with malocclusions and temporomandibular disorders (TMD); to assess the relationship between craniofacial skeletal structures and TMD in subjects with malocclusions. Material and methods: Sixty-four subjects with malocclusions,...

Background and Objectives: The occlusal–temporomandibular disorder (TMD) relation is a contentious issue in dentistry to date. This scoping review’s purpose was to map the existing literature on occlusal abnormalities and their potential role in the development and progression of TMD. Materials and Methods: A search in PubMed, Scopus, Cochrane Library, Embase, Lippincott, Medknow, and ClinicalKey was conducted. Articles researching the relationship between TMD and occlusion have been selected. A narrative data synthesis was conducted to chart and summarize the main findings from the included studies. Results: A total of 29 articles were included in this review. These studies confirm that angle class II and angle class III malocclusions, deep bite, and crossbite have a high prevalence of symptoms of TMD, including mandibular deviation, arthritic pain, and tenderness of the muscles. Malocclusion, edentulous spaces, and a reduced vertical dimension of occlusion (VDO) also contribute to the severity of TMD, most prominently in older adults. TMD is also seen with high prevalence in females, with a female-to-male ratio of 2:1 to 20:1, according to studies. Bruxism, premature occlusal contacts, and occlusal interferences also contribute towards symptoms of TMD, in agreement with multiple facets of the disorder. Conclusions: Occlusal abnormalities have a significant association with TMD, but causality cannot be established with most observational studies. This review emphasizes the need for early occlusal examination and intervention to reduce TMD risk.
