Mandibular Overdenture Retained by Magnetic Assembly: A Clinical tip.

The preservation of remaining root structure and alveolar bone covering them with denture has been used since many years. Tooth-retained overdentures transfer occlusal forces to the alveolar bone through the periodontal ligament of the retained tooth roots and thereby prevent bone resorption. Applications of magnets in overdenture technique has been widely used in dentistry in the field of prosthodontics, as they can be manufactured in small dimensions as retentive devices for complete denture, removable partial dentures, obturators and maxillofacial prosthesis. This article presents a simple and efficient method of fabrication of mandibular over denture retained by magnets in a patient whose mandibular residual ridge is severely resorbed with few remaining teeth and maxillary conventional removable partial denture. Mandibular over denture retained by magnets assembly consist of magnet and coping with keeper on remaining tooth structure to rehabilitate the patient since magnetic attachments can provide support, stability and retention.

Implant esthetic restoration in ridge deficiencies in cases of trauma: a case report.

The long-term success of implant therapy does not depend solely on osseointegration, but the gingival architecture surrounding the implant system. It becomes very important to restore the gingival tissues in the areas that enhance one's esthetics. The esthetic zone can be defined as any dentoalveolar area of esthetic concern to the patient. The anterior maxillary teeth in the esthetic zone usually extend from first premolar to first premolar, but in some individuals can extend as far distally as the first molar. The patients requiring esthetic reconstruction at the site of trauma pose a great problem in implant placement and prosthetic restoration as scar tissue interferes with the same. To be successful, an implant-supported restoration should meet biological, mechanical, and esthetic goals. The most challenging situation is when esthetics is of prime concern in deficient ridge cases. This clinical report presents problems faced during implant placement and the sequential procedure to rehabilitate with an implant that was esthetically harmonized at the site of trauma.

Pterygomaxillary implants: a graftless solution to deficient maxillary bone.

Edentulism is one of the common dental problems in the aging population. Implant therapy has emerged as one the valid and effective solutions to this problem. However in the maxilla, posterior part presents with several anatomic obstacles in the form of bone quality, quantity, size of maxillary antrum and poor accessibility. There are various options like sinus lift with graft and pterygomaxillary implant options available. Option like ptergomaxillary implants requires lot of skill of technic sensitivity and skill of the surgeon and also is proven to be statistically superior. Case reports of pterygomaxillary implants for both partially edentulous and fully edentulous conditions are hereby described in the article.

Rehabilitation of partial maxillectomy defect with implant retained hollow bulb obturator prosthesis: a case report.

Tissue integrated oral implants have initiated a new perspective in oral rehabilitation of tumor patients who have had undergone surgical resection procedure. The present case demonstrated a simple and predictable approach to rehabilitate a patient who had partial maxillectomy using dental implants. The use of an implant in conjunction with hollow bulb obturator shared remarkable improvement in retention and stability of the existing complete denture prosthesis.

Management of velopharyngeal disorders. A case series.

Patients with acquired defects or congenital malformations of the palate exhibit disturbances in speech, including hypernasality, nasal emission, and decreased intelligibility of speech. Maxillofacial prosthetic treatment can reestablish the palatopharyngeal integrity to provide the potential for acceptable speech. This article describes a case series of patients with palatopharyngeal disorders and their treatment approaches.

Efficacy of two gingival retraction systems on lateral gingival displacement: A prospective clinical study.

PURPOSE: Gingival management is a substantive procedure in fixed dental prosthesis treatment. Various new retraction cord systems are available and used. This study aimed to compare the efficacy of a new retraction cord (Stay-Put, Coltene Whaledent AG) and a conventional retraction cord (Ultrapak, Ultradent Products Inc., South Jordan, Utah) on lateral gingival displacement in continuation with the treatment protocol of the subjects fixed dental prosthesis for various partial edentulous conditions requiring fixed dental prosthesis. METHOD: Thirty subjects were selected who needed bilateral fixed dental restoration. In selected subjects both gingival retraction cords were placed bilaterally buccolingually by simple randomization method. After removing the cords, impressions were made and undamaged definitive casts were retrieved. The abutment teeth were sectioned buccolingually at the buccal ridge followed by decimal measurement of the width (in millimeter) of the retracted gingival sulcus, under a traveling microscope. RESULTS: Data was analyzed using SPSS version. Paired "t" test was used to compare the difference between the displaced gingival width in two retraction group (p > 0.05). CONCLUSION: Although mean gingival retraction in Stay-Put system (0.528 ± 0.12 mm) was higher as compared to that in Ultrapak (0.487 ± 0.10 mm), the difference between the two systems (0.041 ± 0.11) was not significant statistically (p = 0.057).
