This review elucidates the advantages and disadvantages of the different implant navigation methods to assist the precise surgical placement of dental implants. Implant navigation surgery can be ...classified into: dynamic and static navigation, and static navigation can further be divided into full (FG)- and half-guided (HG) implant surgery. The HG implant placement includes the drilling-guided, pilot-drill guided, and the non-computed guided approaches. In dynamic navigation, the bone drilling and the implant placement are completely tracked with a specific software; while the static navigation refers to the use of static surgical templates. The FG associated with flapless surgery and teeth/crown supported guides has demonstrated the highest accuracy, followed by the drilling and pilot HG surgery that may provide comparable results, while the non-computer HG and FH implant placement provide the least accuracy in transmitting the implant positioning from the pre-surgical planning to the patient. Additionally, flapless implant surgery is related to reduced pain, less analgesic consumption, less swelling, shorter chair-time, and reduced risk of hemorrhage while achieving greater patient satisfaction. Nevertheless, other methods such as non-computer HG and FH implant surgery procedures require more surgical experience to overcome their limitations. There is still limited evidence to support dynamic surgery, and further investigations are needed.
In this comprehensive evaluation, ten experienced oral surgeon experts posed a total of twenty oral surgery-related questions, including dental implant and tooth extractions, to three distinct ...Natural Language Processing (NLP)-based chatbot platforms: ChatGPT, Microsoft Bing, and Google Bard. The study aimed to assess the effectiveness of these chatbots in responding to specialized medical questions.
Two primary evaluation metrics were employed: a Likert Scale (LS) for measuring the accuracy and completeness of responses and a Global Quality Scale (GQS) for evaluating the clarity of responses. Statistical analyses, including one-way analysis of variance (ANOVA) and Post Hoc Tukey, were conducted to assess and compare the performance of the chatbots as rated by the experts.
The results of the study revealed significant differences in the performance of the chatbots. ChatGPT statistically achieved a better mean LS score of 1.4000±0.15986 than Microsoft Bing (1.8750±0.18143) and Google Bards (2.0500±0.12472) (P < 0.001). Additionally, ChatGPT statistically achieved a higher GQS score of 4.4200±0.30111 than Microsoft Bing (3.7550±0.28621) and Google Bards (3.5250±0.22392) (P < 0.001).
These findings showed the substantial advantage of ChatGPT in effectively addressing oral surgery-related questions with superior accuracy, completeness, and clarity. The study highlights the potential of advanced NLP platforms to enhance information retrieval and communication within the field of oral surgery, reinforcing the utility of such technologies in medical and surgical domains.
The coronavirus disease 2019 (COVID-19) pandemic has had an immense impact on the healthcare industry. Oral and maxillofacial surgery (OMS) clinical practice uniquely exposes providers to COVID-19. ...The purpose of the present study was to understand the effect of the COVID-19 pandemic on OMS residency training programs (OMSRTPs): 1) training and education; 2) availability and use of personal protective equipment (PPE); 3) experience with, and use of, screening and viral testing; 4) resident experience; and 5) program director (PD) experience and observations of the immediate and future effects on OMSRTPs.
OMS residents and PDs in OMSRTPs in the United States were invited to participate in the present cross-sectional study from April 1, 2020 to May 1, 2020. A 51-question survey was used to evaluate the effects of COVID-19 on OMSRTPs and to assess the 5 specific aims of the present study.
A total of 160 residents and 13 PDs participated in the survey, representing 83% of US states or territories with OMSRTPs. Almost all residents (96.5%) reported modifications to their training program, and 14% had been reassigned to off-service clinical rotations (eg, medicine, intensive care unit). The use of an N95 respirator mask plus standard PPE precautions during aerosol-generating procedures varied by procedure location, with 36.8% reporting limited access to these respirators. Widespread screening practices were in use, with 83.6% using laboratory-based viral testing. Residents scheduled to graduate in 2022 were most concerned with the completion of the graduation requirements and with decreased operative experience. Most residents (94.2%) had moved to web-based didactics, and a plurality (47%) had found increased value in the didactics.
Sweeping alterations to OMS clinical practice have occurred for those in OMSRTPs during the COVID-19 pandemic. Although the overall OMSRTP response has been favorable, residents' concerns regarding the ubiquitous availability of appropriate PPE, operative experience, and completion of graduation requirements requires further deliberation.
3D and 4D printing are cutting-edge technologies for precise and expedited manufacturing of objects ranging from plastic to metal. Recent advances in 3D and 4D printing technologies in dentistry and ...maxillofacial surgery enable dentists to custom design and print surgical drill guides, temporary and permanent crowns and bridges, orthodontic appliances and orthotics, implants, mouthguards for drug delivery. In the present review, different 3D printing technologies available for use in dentistry are highlighted together with a critique on the materials available for printing. Recent reports of the application of these printed platformed are highlighted to enable readers appreciate the progress in 3D/4D printing in dentistry.
Additive manufacturing is the process of joining materials to create objects from digital 3-dimensional (3D) model data, which is a promising technology in oral and maxillofacial surgery. The ...management of lost craniofacial tissues owing to congenital abnormalities, trauma, or cancer treatment poses a challenge to oral and maxillofacial surgeons. Many strategies have been proposed for the management of such defects, but autogenous bone grafts remain the gold standard for reconstructive bone surgery. Nevertheless, cell-based treatments using adipose stem cells combined with osteoconductive biomaterials or scaffolds have become a promising alternative to autogenous bone grafts. Such treatment protocols often require customized 3D scaffolds that fulfill functional and esthetic requirements, provide adequate blood supply, and meet the load-bearing requirements of the head. Currently, such customized 3D scaffolds are being manufactured using additive manufacturing technology. In this review, 2 of the current and emerging modalities for reconstruction of oral and maxillofacial bone defects are highlighted and discussed, namely human maxillary sinus floor elevation as a valid model to test bone tissue-engineering approaches enabling the application of 1-step surgical procedures and seeding of Good Manufacturing Practice–level adipose stem cells on computer-aided manufactured scaffolds to reconstruct large bone defects in a 2-step surgical procedure, in which cells are expanded ex vivo and seeded on resorbable scaffolds before implantation. Furthermore, imaging-guided tissue-engineering technologies to predetermine the surgical location and to facilitate the manufacturing of custom-made implants that meet the specific patient's demands are discussed. The potential of tissue-engineered constructs designed for the repair of large oral and maxillofacial bone defects in load-bearing situations in a 1-step surgical procedure combining these 2 innovative approaches is particularly emphasized.
