Bone formation in small deposits following the loss of part of the mandible has often been reported in the literature, but the long-term follow-up reports of bone regeneration extending over the mandible are rare. Even rarer, are reports on the behavior of such new bone in terms of facial development, over a long period and the effect of load on it. A unique case of bone regeneration after resection of a large portion of the mandible in a 9-year-old male patient with myxofibrosarcoma in the body of the mandible is presented here. Intermaxillary fixation and insertion of reconstruction plate after resection without continuity defect were employed. Spontaneous bone regeneration was noted 8 weeks after surgery, and the resected portion of the mandible was regenerated when the patient was seen again 7 years later. Mandibular growth was not significantly affected and almost 7 years after his treatment, without relapsing of pathologic condition, the shape of the mandible is satisfactory without any evidence of bone resorption.

Anterior teeth fracture is a common form of dental trauma that mainly affects children and adolescents. Maxillary incisors are the most commonly affected teeth. Loss of coronal tooth structure might affect esthetics and function. In recent decades, dentistry has shown many scientific and technological advances in restorative materials. However, no synthetic restorative material can replicate the natural tooth structure. Hence, the use of natural tooth as a restorative material has been suggested in literature and is termed as a biological restoration. The present case report represents the successful use of biological post and crown and was adequate with respect to adhesion, function, and esthetics with the follow-up period of 1 year. Hence, it may be concluded that the biological restoration, if feasible, is a cost-effective way to restore a damaged tooth with acceptable esthetics and tooth functions in the stomatognathic system.

Mandibular canal is the most important anatomical landmark in the body of mandible which always must be considered for implant surgery in posterior mandibular region. Damage to vessels and inferior alveolar nerve that passes through the mandibular canal can cause problems such as hemorrhage and neurosensory disturbances. Damage to the mandibular canal can occur during implant surgery. Depending on the severity of injuries, it would result in temporary or permanent neurosensory disturbances. We have reported a case that mandibular canal narrowing occurred following implant surgery and resulted in anesthetic and hypoesthetic areas in the lower lip. Patient had a history of implant surgery in the region of teeth numbered 30 and numbered 31. The inserted implant failed after 6 years, and reimplantation was done in this area, but due to lower lip numbness in the right side, the second implant was removed, and another implant was inserted in the region of the tooth numbered 32. After 2 years, right lower lip numbness was reported again by the patient. Cone beam computed tomography images showed canal narrowing in the region of the tooth numbered 31 where the second implant was inserted. It seems that the main cause for anesthesia and hypoesthesia in this patient is canal narrowing due to damage during implant replacement and removal.

Desmoplastic fibroma (DF) is a rare benign but aggressive fibrous lesion with an unknown etiology. It has an affinity for the mandible. DF has a high rate of recurrence after surgical resection. In this study, we report the therapeutic management of a recurrence of DF in the lower jaw in a 2-year-old boy. He responded well to second surgical intervention with wide resection and immediate reconstruction with plate. The purpose of this case report is to emphasize the particularity of the case, treatment modalities, and differential diagnosis in DF.

Microstomic patients may experience a significant limitation in the mandibular opening. The prosthetic rehabilitation of microstomic patients presents difficulties at all stages, from preliminary impressions to prosthetic fabrication. This clinical report described the method of fabrication of sectional denture for patients with microstomia caused by burns. The denture was fabricated in two pieces, and patients inserted and removed the denture easily.

Periodontal surgery associated with prior waxing, mock-up, and the use of digital tools to design the smile is the current trend of reverse planning in periodontal plastic surgery. The objective of this study is to report a surgical resolution of the gummy smile using a prior esthetic design with the use of digital tools. A digital smile design and mock-up were used for performing gingival recontouring surgery. The relationship between the facial and dental measures and the incisal plane with the horizontal facial plane of reference were evaluated. The relative dental height x width was measured, and the dental contour drawing was inserted. Complementary lines are drawn such as the gingival zenith, joining lines of the gingival and incisal battlements. The periodontal esthetic was improved according to the established design digital smile pattern. These results demonstrate the importance of surgical techniques and are well accepted by patients and are easy to perform for the professional. When properly planned, they provide the desired expectations. Periodontal Surgical procedures associated with the design digital smile facilitate the communication between the patient and the professional. It is, therefore, essential to demonstrate the reverse planning of the smile and periodontal parameters with approval by the patient to solve the esthetic problem.

Rehabilitation of patients with a severe mandibular defect is challenging to prosthodontists. The esthetic and functional rehabilitation of patients with lateral mandibular resection is difficult due to the lack of supporting tissues for the prosthesis. The mandibular deviation furthermore results in facial asymmetry and unstable occlusion. This case report describes an innovative technique to rehabilitate a patient with lateral mandibular resection using customized access post attachment system to retain guide flange prosthesis for reducing mandibular deviation.
