Usefulness of Magnetic Mallet in Oral Surgery and Implantology: A Systematic Review

This systematic review aimed to answer the question: “Is the use of magnetic mallet effective in oral and implant surgery procedures in terms of tissue healing, surgery outcome, and complication rate compared to traditional instruments?” A literature search of PubMed, Scopus, and Web of Science databases (articles published until 1 October 2021) was conducted, in accordance with the PRISMA statement, using the keywords “magnetic mallet”, “electric mallet”, “oral surgery”, “implantology”, and “dental implant”. Of 252 articles, 14 were included in the review (3 for teeth extraction, and 11 for implant dentistry). Out of a total of 619 dental extractions (256 patients) performed with the magnetic mallet (MM), no complications were reported. Implants inserted totaled 880 (525 patients): 640 in the MM groups (382), and 240 in control groups (133). The survival rate of implants was 98.9% in the MM groups, and 95.42% in the control groups. Seven patients experienced benign paroxysmal positional vertigo after implant surgery, all in control groups. Results are not sufficient to establish the effectiveness of MM in oral and implant surgery procedures. Randomized controlled trials with a large sample size are needed.

Application of 3D printing and its various technologies in dentistry

Many applications for these technologies have been reported in multiple fields, including dentistry, within the last three decades. It can be used in periodontology, endodontics, orthodontics, oral implantology, maxillofacial and oral surgery, and prosthodontics. In the present literature review, we have discussed the different clinical applications of various 3D printing technologies in dentistry. Evidence indicates that 3D printing approaches are usually associated with favorable outcomes based on the continuous development and production of novel approaches, enabling clinicians to develop complex equipment in different clinical and surgical aspects. Developing work models to facilitate diagnostic and surgical settings is the commonest application of these modalities in dentistry. Besides, they can also be used to manufacture various implantable devices. Accordingly, they significantly help enhance the treatment process, reducing costs and less invasive procedures with favorable outcomes. Finally, 3D printing technologies can design complex devices in a facilitated and more accurate way than conventional methods. Therefore, 3D printing should be encouraged in clinical settings for its various advantages over conventional maneuvers.

Evaluating the Relationship between Mandibular Third Molar and Mandibular Canal with Semiautomatic Segmentation: A Pilot Study on CBCT Datasets

Inferior alveolar nerve injury is the main complication in mandibular third molar surgery. In this context, cone-beam computed tomography (CBCT) has become of crucial importance in evaluating the relationship between mandibular third molar and inferior alveolar nerve. Due to the growing interest in preoperative planning in oral surgery, several post-processing techniques have been implemented to obtain three-dimensional reconstructions of a volume of interest. In the present study, segmentation techniques were retrospectively applied to CBCT images in order to evaluate whether post-processing could offer better visualization of the structures of interest. Forty CBCT examinations performed for inferior third molar impaction were analyzed. Segmentation and volumetric reconstructions were performed. A dataset composed of multiplanar reconstructions for each study case, including segmented images, was submitted for evaluation to two oral surgeons, two general practitioners and four residents in oral surgery. The visualization of root morphology, canal course, and the relationship with mandibular cortical bone on both native CBCT and segmented images were assessed. Inter-rater agreement showed values of intraclass correlation coefficient (ICC) above 0.8 for all the examined parameters. Oral surgeons presented higher ICC values (p < 0.05). Segmented images can improve preoperative evaluation of the third molar and its relationship with the surrounding anatomical structures compared to native CBCT images. Further evaluation is needed to validate these preliminary results.

Including Shareholders to Your Private Practice in Oral Surgery and Dentistry: Ukrainian Laws

Dental clinic/office launch and development is non-easy task, which require not only a lot of efforts but also some level of the investments, especially for the commercial real estate and expensive equipment. And very often the amount of finances which one person or family is bringing to business may not be sufficient. Including of shareholders can help to reach that goal. Including the partners (ie, cofounders or shareholders) to your private clinic/ office in a legal form of Limited Liability Company (LLC) are possible upon two stages: (1) upon the business launch and (2) upon the business existence. The second variant is more complicated and has to be analyzed.

Prosthodontic Rehabilitation of Hypodontia – A Team Approach

Hypodontia can have an impact on speech, aesthetics, function and psycho-social behavior of individuals afflicted by the problem. Rehabilitation of patients with hypodontia usually requires complex treatment planning, depending upon the pattern of tooth absence, amount of residual spacing, presence of malocclusion and patient compliance. It is an interdisciplinary intervention, involving prosthodontists, orthodontists, oral surgeons, speech pathologists and psychologists to achieve an optimal outcome for the patient. This case report describes the close work of a committed team from orthodontic, oral surgery and prosthodontic department of de'Montmorency College of Dentistry, Lahore, to reach final aesthetic and functional outcomes for an 18 year old girl with oligodontia. Her chief complaint was poor esthetics and absence of multiple anterior teeth with unsightly spacing between remaining teeth. Orthodontic redistribution of spaces followed by fixed full arch prosthetic rehabilitation were the goals achieved at the end of her treatment. KEYWORDS: Oligodontia, interdisciplinary team work, prosthodontic rehabilitation, fixed restorations.

Perception and Attitude of Dental Students and Interns Regarding the Diagnosis and Management of Oral Mucosal Lesions and Salivary Glands Hypofunction

Background: The perception and attitude of dental students/graduates regarding diagnosing/managing oral medicine cases are scarcely investigated. Objective: The aim of this investigation was to evaluate the level of confidence in diagnosing/managing cases of oral mucosal lesions and salivary glands hypofunction. Methods: A 29-items questionnaire descriptive survey was distributed among dental interns and sixth-year students in the city of Jeddah during March-April of 2020. Results: A total of 136 (81 interns and 55 sixth-year students) completed the questionnaire, of which 69.9% were from a government school, and 30.1% were from private schools. For oral mucosal lesions [i.e., aphthous/herpes simplex virus ulceration], the majority of government and private schools’ participants reported being confident in their ability to diagnose (88.4% and 87.8%, respectively) and provide treatment (63.2% and 56.1%, respectively). For oral candidiasis, the majority were confident in their ability to diagnose (government: 95.8%; private: 59.1%) and treat (government: 77.9%; private: 65.9%). The confidence in diagnosing lesions suspicious for dysplasia/premalignancy was high in 77.9% of government and 80.5% of private schools. Similar reporting was found regarding salivary hypofunctions (government: 93.7%; private: 90.2%). For the likeness to refer, the majority of participants were likely to refer to oral medicine, as the 1st choice, followed by oral surgery. Conclusion: Dental interns/sixth-year students seemed to have high levels of confidence in diagnosing/managing oral mucosal lesions and salivary hypofunctions. However, the partial participation and the subjectivity of reporting may have hindered capturing the full/precise picture.
