The purpose of this study was to evaluate the efficacy of bone ring augmentation technique for three-dimensional augmentation of severely defective sockets along with placement of immediate dental implants.A clinical study was conducted on 14 patients with 15 defective sockets requiring extractions and immediate implant placement. Following extraction, bone ring with an implant osteotomy, harvested from chin, was sculptured and fitted into the extraction socket. The bone apical to the socket was prepared for implant through the central osteotomy of the ring. Implant was then placed through the ring into the apical bone. After 6 months, prosthesis was placed. Clinical and radiographic examination was done to evaluate the soft tissue and crestal bone level around implants immediate postoperatively and at 1st, 3rd, 6th, and 9th month postoperatively.Out of 15 grafted sockets, 14 showed an evidence of bone healing with no significant crestal bone resorption. One ring showed soft tissue dehiscence which underwent severe resorption at 6th month postoperative visit.The bone ring augmentation technique is an effective method for three-dimensional augmentation of severely defective sockets. This technique helps in reducing the overall treatment time by allowing grafting and placement of implant simultaneously in a single visit. However, longer observation periods are needed to draw more definite conclusions on the success of bone ring augmentation technique.

即刻种植周围骨环增强：一项临床和放射学研究

Abstract Rationale: Intraparotid facial nerve schwannoma (IPFNS) is a rare entity. Diagnosing these tumours is challenging as multiple differential diagnoses exist for swellings in the infraauricular region. Delay in diagnosis can lead to adverse outcomes. Patient Concerns: A 27-year-old female presented with swelling over the left infraauricular region, which concerned her cosmetic appearance. Diagnosis: It was initially misdiagnosed with imaging techniques computerised tomography (CT scan) and fine-needle aspiration cytology, leading to a diagnostic dilemma. Treatment: Superficial parotidectomy was planned and intraoperatively, a cystic lesion was seen adherent to the temporal branch of the facial nerve, which was resected along with the nerve branch. Histopathology confirmed the diagnosis as facial nerve schwannoma. Outcomes: The patient’s cosmetic concern was resolved but there was loss of wrinkles over the ipsilateral forehead region. No recurrence was seen. Take-Away Lessons: IPFNS often causes a diagnostic dilemma and an appropriate and timely diagnosis is required to decrease the morbidity and undertreatment.

Abstract Introduction: This study aims to advance evidence-based implant dentistry through a meticulous assessment of clinical and radiographic outcomes of two implant techniques, providing valuable insights for clinicians and researchers on their long-term success. Materials and Methods: A 5-year, split-mouth, randomised, double-blind clinical trial with 40 volunteers compared Group A (flapless technique) and Group B (standard flap technique) across 40 sites each. Clinical and radiographic assessments were conducted, and data were analysed using SPSS Version 22.0 with a significance level of P &lt; 0.001. Results: Participants aged 21–49 years showed that Group A (flapless) had higher baseline marginal bone loss but significantly less bone loss from 1 to 5 years compared to Group B ( P &lt; 0.001). Group A also had lower Visual Analogue Scale scores and analgesic intake from day 0 to day 5 ( P &lt; 0.001). Both groups had a 100% implant survival rate at 5 years, but Group A had higher patient satisfaction ( P &lt; 0.001). The diverse cohort of 40 participants included 50% from urban areas and 17.5% with high professional qualifications, all showing good oral hygiene. Discussion: Flapless implant surgery aligns with minimally invasive dentistry, reducing surgical trauma, improving aesthetics, shortening surgery time and enhancing patient satisfaction. It is suitable for various patient groups and represents a strategic shift in practices, especially in sites with favourable soft- and hard-tissue conditions.

Abstract Rationale: Mesiodens are supernumerary teeth located in the pre-maxilla between the two central incisors with a prevalence rate of 0.15–1.9%. An impacted mesiodens may cause delayed eruption of permanent incisors, ectopic eruption, pathological disturbances and malalignment of teeth. Patient Concerns: The patient complained of missing upper front teeth associated with pain in the same region for two weeks. Diagnosis: Upon clinical and radiographic examination, it was diagnosed as triple impacted mesiodens with impacted permanent maxillary central incisors. Treatment: The clinicians in the study approached the issue by surgical removal of the impacted mesiodens and orthodontic treatment for extrusion of the impacted permanent maxillary central incisors. Outcomes: The patient was relieved of the pre-operative concerns and followed up regularly for the eruption of permanent maxillary central incisors. Take-away Lessons: The authors advocate the importance of timely diagnosis and proper management of such rare pathologies.

正畸-外科联合治疗三颗埋伏中切牙及上颌切牙——一例报告

Sclerosing agents have been used for temporomandibular joint (TMJ) hypermobility since decades, some of which are ethanolamine oleate, and OK-432, sodium psylliate (sylnasol), but there are no studies on the usage of polidocanol - a well-known sclerosing agent which does not have much side effects and is inexpensive. Hence, this study evaluates the effect of polidocanol injection in the treatment of TMJ hypermobility.This was a prospective observational study in which patients with chronic TMJ hypermobility were included. Out of the 44 patients who had symptoms of clicking and pain of the TMJ, 28 were diagnosed as internal derangement of the TMJ. The final analysis included 15 patients in whom multiple injections of polidocanol were given on the basis of post-operative parameters. The sample size was calculated based on a significance level of 0.05 and a power of 80%.Overall, a success rate of 86.6% (13/15) was encountered at the end of three months, with seven patients not reporting any further episodes of dislocation after one injection and six patients not reporting any episode of dislocation after two injections.Polidocanol sclerotherapy can be used as a treatment modality for chronic recurrent dislocation of the TMJ, rather than opting for more invasive procedures for the same.

Abstract Introduction: The purpose of this study is to compare and infer the most suitable dye for visualisation of ipsilateral and contralateral sentinel lymph nodes (SLNs), positive, negative outcomes, sensitivity, their specificities and visualisation of anastomosed blood vessels in microvascular reconstruction of tongue cancers. Materials and Methods: This is a prospective in vivo comparative study involving twenty patients diagnosed with squamous cell carcinoma of the tongue treated with wide excision of primary tongue tumour, modified functional neck dissection and microvascular reconstruction with radial forearm free flap. Consecutive random allocation was done into two groups with ten patients each. Patients were injected with methylene blue as the first group and near-infrared fluorescence indocyanine green (ICG) into the second. The patients were evaluated intraoperatively regarding the better dye in methylene blue and ICG for identification of ipsilateral and contralateral SLNs, their positive, negative outcomes, sensitivity and specificities. Apart from these, in cases of group B, after microvascular transfers, ICG is used for visualisation of anastomosed vessels to prevent abnormal perfusions, leaks and post–flap failures. Descriptive statistics, independent samples t -test, and Chi-square were used for statistical analysis. Results: The present study revealed ICG being the better dye in the parameters mentioned. Discussion: Lymph node yield in neck dissection is a prognostic factor in oral cancers. ICG is inferred as the better dye for identification of SLN with 100% outcomes and in blood vessel visualisation after microvascular free tissue transfers. It is also useful in identifying positive contralateral sentinel nodes, which is helpful in undertaking bilateral neck dissections related to tongue carcinoma.

自由瓣舌癌切除与重建中重要染色作用——一项比较研究

Abstract Introduction: The objective of this study was to assess the vertical loop of the inferior alveolar nerve (IAN) at the mental foramen region by measuring the vertical height of the loop from the lower border of the IAN canal to that of the lower border of the mental foramen using cone-beam computed tomography (CBCT) scan. Materials and Methods: A retrospective study was conducted using CBCT scans of 541 patients aged 18 years and above from March 2015 to March 2022. These scans were analysed to determine the height of the vertical loop of IAN at the mental foramen. Results: Statistically significant value was obtained, with the highest value being 11.6 mm and a mean value of 3.81 mm. The right-side vertical loop of IAN at the mental foramen region was significantly higher in males (3.92 ± 1.78) than in females (3.59 ± 1.42). Statistically significant results were obtained on both sides amongst the different age groups. Discussion: The vertical loop at the mental foramen region is considered to be significant for planning and performing various oral and maxillofacial surgical procedures. A CBCT is a must, but in its absence, a safety zone of 7–10 mm is to be allowed to prevent inadvertent nerve damage.
