Laboratory Validation of a Novel Indigenously Developed Bite Force Measuring Device.

INTRODUCTION: It is critical to measure the maximum voluntary bite force of patients receiving restorative dentistry. A new device known as "BYTE" has been developed indigenously to measure bite force in humans. The purpose of this study is to evaluate the BYTE device's consistency and accuracy in a lab setting. METHODOLOGY: Testing and calibration were done in the laboratory. The calibration machine with load cell pressed the biting part of the device with various forces from 3 N to 444 N in 3 N increments for two to three seconds each. The recorded force value in Newton by the device was noted down. RESULTS: At numerous standard loads, the minimum accuracy error is 0.333 N, while the maximum is 1.667 N. It marginally underestimates the load with an average accuracy error of 0.833 N. CONCLUSION: The calibration report showed that the BYTE device is precise and reliable and can be used to measure maximum bite force.

Comparative Assessment of Crestal Bone Levels in Immediate Versus Delayed Implant Placement With and Without Bone Graft.

Background Presently, modern regenerative and surgical techniques for immediate implant placement in prepared sockets with soft tissue grafts and bone substitutes have helped eliminate concerns about bone deficiency. This also allowed the placement of dental implants based on prosthodontic needs. Aim  The present study aimed to comparatively assess dental implant healing following immediate implant placement with or without bone graft and dental implant healing after delayed implant placement with or without bone graft. Methods The study included 120 study subjects that were divided into two groups. Group I for immediate implant placement with or without bone graft (n=60) and Group II for delayed implant placement with or without bone graft (n=60). These two groups were further divided into subgroups. Group I subjects were further divided into two subgroups, where Group A (n=30) subjects underwent immediate implant placement with bone graft and Group B (n=30) subjects were given immediate implant placement without bone graft. Group II participants were further divided into two subgroups, where Group C (n=30) subjects underwent delayed implant placement with bone graft and Group D (n=30) subjects underwent delayed implant placement without bone graft. In the two groups, crestal bone levels were compared radiographically preoperatively and postoperatively at the immediate postoperative time, three months, and six months. Results More reduction in the crestal bone level was seen in the immediate implant placement group at three and six months postoperatively compared to the delayed implant placement group. A non-significant reduction in crestal bone levels was seen in the immediate implant placement with bone graft group with p>0.05 at three and six months compared to immediate implant placement without bone graft. Similar, non-significant crestal bone loss was seen in the delayed implant placement with bone graft group at three and six months compared to delayed implant placement with bone graft. Conclusions  This study concluded that healing of crestal bone in the delayed implant placement group with or without bone graft is better in comparison to the immediate implant placement group with or without bone graft.

An Innovative Technique for Assessment of Bone Change, Bite Force, and Retention of the Single-Implant-Supported Mandibular Overdenture: A Clinical Study.

This study is the first study to incorporate a novel approach to single-implant-retained mandibular overdenture with a bar attachment on a single implant in the symphysis region. The use of a single-implant-retained bar overdenture significantly improved patients' chewing efficiency, indicating enhanced overdenture retention and stability. Materials and Methods: Ten maxillary and mandibular completely edentulous patients were enrolled in the study. A complete denture was fabricated for them. On completion, bite force, retention force, and bone change were recorded. Bite force was recorded with the strain gauge, retention force with the force measurement gauge, and bone changes with radiographs. Conclusion: Single-implant-supported bar mandibular overdenture (SISBOD) can be a suitable standard economic option for edentulous mandible and can greatly improve the quality of life of patients.

A Systematic Review on Prosthodontic Rehabilitation of Hemimandibulectomy Defects.

Restoration of hemimandibulectomy defects following tumour extirpation to restore oral function is a herculean task for practitioners. Prosthetic treatment alternatives available for rehabilitation of acquired hemimandibulectomy defects according to mandibular reconstruction type and extent (Cantor-Curtis classification) are unclear. This systematic review aims to assess the spectrum of prosthodontic rehabilitation approaches with regard to reconstruction type and extent of mandibular surgical defects. The databases incorporated for literature search were Google Scholar and Medline (PubMed). Relevant search terms for hemimandibulectomy and reconstruction with prosthetic rehabilitation were used. Two reviewers independently assessed the articles using eligibility criteria; published case reports and case series in the English language and depicting prosthodontic treatment modality of patients greater than 15 years were included. A total of 202 records were identified from the database search of which 19 duplicates were removed. The remaining articles were assessed for eligibility, and 55 articles (comprising 58 cases) were finally included in the study. This review revealed various prosthetic alternatives ranging from guide flange, twin occlusion, palatal ramp, conventional to hybrid partial and complete dentures to implant-supported prosthesis including a few innovative prosthetic approaches. This systematic review provides a plethora of prosthodontic rehabilitation approaches according to the extent of hemimandibular surgical defect and type of reconstruction. This will facilitate practitioners and prosthodontists in sequential treatment planning and management of hemimandibulectomy cases in their routine practice.

Incidence of Canine Impaction in Tribal Population of Jharkhand.

Introduction: The position of the canine has a key role in facial harmony, dental aesthetics, functional occlusion, and health of temperomandibular joint. Maxillary canine impaction is the second most common tooth after third molars impaction. Maxillary canines are more prone to impaction due to longer path of eruption. Settings and Design: All the patients were examined in the Dental Chair light and referred to the department of Oral Radiology for Orthopantomogram. Yamamoto's classification was used to classify maxillary canine impaction. Position of mandibular canine from cement-enamel junction was used for mandibular canine impaction. Materials and Methods: The study was performed on 2300 patients who consulted the orthodontic department from January 2018 to July 2022. Orthopantomogram of each patient was examined for canine impaction, retained deciduous teeth, cyst, and other anomalies. The incidence and pattern of canine impaction was assessed. Statistical Analysis: The data was then statistically analyzed using Graph Pad Prism software. The incidence of impacted canine was evaluated. The effect of gender was evaluated using a t-test. Results: A total of 2300 subjects were examined out of which 52 individuals were diagnosed with canine impaction. The incidence of canine impaction among orthodontic patients is 2.26%. The amount of canine impaction in females (60%) is higher than males (40%). The ratio of canine impaction of the maxilla and mandible is 2.5. Conclusion: The incidence of canine impaction was found to be 2.26 percent in the tribal dominant population of Jharkhand. Type II (50%) pattern in the maxilla and Level A (57%) impaction in the mandible was found to be the highest.

Quantifying the Release of Titanium From the Titanium Dioxide-Impregnated Composites Used in Orthodontic Bonding.

BACKGROUND: Previous literature data has extensively assessed the biocompatibility of various orthodontic adhesives and their components, where the results of most of the studies showed cytotoxic effects of different degrees owing to the unbound molecules released structurally from the cured components. AIM: The present in-vitro study was aimed to assess the release of titanium dioxide nanoparticles in the artificial saliva from the orthodontic composites impregnated with titanium dioxide nanoparticles of 5% w/w (weight/weight) and 1% w/w used for metal brackets bonding. METHODS: The study assessed 160 teeth extracted freshly during orthodontic treatment and divided into two groups of 80 samples, each that bonded to orthodontic brackets having 5% w/w and 1% w/w composites with titanium dioxide nanoparticles kept in the artificial saliva. Quantification was done for 5% w/w and 1% w/w composites having titanium nanoparticles with inductively coupled plasma mass spectroscopy at 24 hours, two, four, and six months. RESULTS: It was seen that in teeth with 1% titanium dioxide, the greatest titanium release was seen at two months, with non-significant release after two months. In teeth with 5% w/w titanium dioxide nanoparticles showed significant titanium release all the time. A significantly greater titanium dioxide release on increasing concentration from 1% to 5% was seen for the 5% w/w group at all the assessment times. CONCLUSION: The present study concludes that a higher release of titanium is seen in 5% w/w composite containing titanium dioxide nanoparticles, and the concentrations of 1% and 5% can be safely used and are considered to be within permissible limits.

Efficacy of Two Types of Noninvasive Nerve Stimulation in the Management of Myofascial Pain Caused by Temporomandibular Joint (TMJ) Disorders.

Background A range of diseases affecting the jaw muscles and/or temporomandibular joint are referred to as temporomandibular disorders (TMDs). Nearly 80% of the general population is affected by TMDs, and 48% of those people have trouble opening their mouths and have painful muscles. Aim To compare the effectiveness of transcutaneous electrical nerve stimulation (TENS) and microcurrent nerve stimulation (MENS) for the relief of masticatory muscle discomfort. Methods Groups I and II were further separated into two groups of 30 persons each (A and B), as well as subgroups C and D. Subjects in Group I received TENS treatment for 20 minutes at frequencies of 0-5 and 5-5 for subgroups A and B, and with visual analog scale (VAS) scores of 1-5 and 6-10 for subgroups C and D, respectively. Subjects in Group II received MENS for 20 minutes, with subgroups C and D receiving the same frequency and VAS score as subgroups A and B, respectively. All individuals underwent treatment with a comparable frequency and length of time every day for five days. Results For subgroup D treated with MENS, there was a considerable reduction in pain; however, for subgroups A and C, there was a comparable reduction in the VAS score for both groups treated with MENS and TENS therapy. Conclusion Compared to TENS, MENS provides quicker and more effective pain relief. Paresthesia and tingling are two adverse effects of TENS that are not present with MENS. However, MENS and TENS are equally helpful at treating masticatory muscle discomfort that is both acute and chronic, as well as improving mouth opening.

Early Management of Class III Malocclusion in Mixed Dentition.

AIM: Skeletal class III malocclusion are the most challenging orthodontic problem to treat. Diagnosis and treatment in early stage was important to boost self-esteem of patient. Our aim was to correct skeletal relationship and anterior crossbite to enhance the growth of maxilla. BACKGROUND: Class III malocclusion can be due to retrognathic maxilla, prognathic mandible or combination. Complexity of class III malocclusion depends upon abnormal growth pattern of maxilla and mandible. Maxilla growth ceases around 8-10 years and mandible continue till 16 years. Early intervention boosts self-esteem of the patient. CASE DESCRIPTION: This case presents with clinical feature of retrognathic maxilla at the age of six years. The patient had concave profile with incompetent lips. The mentolabial sulcus was normal and obtuse nasolabial angle with high clinical Frankfurt mandibular angle (FMA). There was reverse overjet of 1 mm. Cephalometric analysis showed a class III skeletal pattern with retrognathic maxilla and orthognathic mandible with increase in lower facial height and increases in gonial angle. The rapid maxillary expansion (RME) with reverse pull face mask was planned. The expansion screw was activated to loosen the circumaxillary suture. CONCLUSION: After active treatment anterior crossbite was corrected. The patient sagittal discrepancy was improved. Early mixed dentition period is the best time to begin class III treatment. CLINICAL SIGNIFICANCE: Early treatment with maxillary protraction and palatal expansion can correct most anterior-posterior skeletal discrepancy. HOW TO CITE THIS ARTICLE: Jha AK, Chandra S.
