A New Trend in Recording Subgingival Tissue around an Implant While Making a Direct Abutment Impression

A successful implant-supported restoration must provide adequate function and esthetics. Osseointegrated implants have given an alternative choice for patients who have lost their teeth. Most commonly encountered problems while doing a transfer from patient to the master cast in restoring implant-supported crowns are an uneven distribution of occlusal loads and undue torquing forces on the various elements of implant. This is caused due to poor fit of frameworks connected to implant, which further leads to marginal bone loss, loosening of screws, fatigue fracture of implant components, and ultimately implant failure. This paper presents a simplified and easy solution to overcome such problems by introducing an innovative gingival retraction system for restoring implant-supported crowns to achieve superior and predictable long-term outcomes

A sectional-splinting technique for impressing multiple implant units by eliminating the use of an open tray

Since the inception of root form implant dentistry by P-I Branemark in the early 1980′s, so many technical advances have been put forward by several authors. However, the open tray impression technique is still performed for impressing multiple implant fixtures as it was first described in the original Branemark procedure manual. The most critical aspect for a successful implant-supported restoration is the passive and an accurate fit of superstructures to avoid preload and loading stresses. Splinting impression technique in multiple implants has gained popularity. Auto-polymerizing acrylic resin is among the most routinely practiced splinting material for multiple implant units. However, unfortunately, it exhibits shrinkage, which makes an impression quite inaccurate. This case report presents the solution to minimize the shrinkage of resin by utilizing sectional-splinting technique as advocated in the previous implant literature

Nonsyndromic Familial Oligodontia with Multiple Dens Invaginatus: A Case Report of an Unusual Case

Oligodontia is a rare dental anomaly with a prevalence of 0.3% in permanent teeth and much less frequency in the primary dentition. Familial oligodontia represents an absence of varying numbers of primary and/or secondary teeth as an isolated trait. It is a complex and multifactorial condition. Many explanations—evolutionary, genetic, and environmental—have been proposed as the etiology. Simultaneous with oligodontia are often the different positional changes of the existing teeth, their morphology, size, and growth disturbances of the maxillofacial skeleton. Early recognition is vital to provide adequate treatment and prevent squeal. Multidisciplinary referral or consultation is thus important in treatment planning to improve function and esthetics. The present paper reports a rare case of familial oligodontia associated with multiple dense invaginatus and microdontia

Brief Communication Wire Cutter: Improvised approach with Basic Instrument

ABSTRACT A good armamentarium is basic to a practicing oral and maxillofacial surgeon. Various instruments and equipment are being improvised on a continuous basis to curtail various inherent problems and disadvantages of these instruments. The wire cutter is one such instrument, which is used in day-to-day oral surgical practice and is not free of disadvantage like blunting of sharp edges as a result of repeated usage and sterilization process. In this article, we discuss about a commonly used basic instrument (nail cutter) which can be efficiently used as a wire cutter

A Large Multifocal Aggressive Osteoblastoma of Mandible: an Immunohistochemistry Case Study Report

Aggressive osteoblastoma (AO) is a benign osteoblastic tumor which is rare in the head and neck region. Clinical and histological features are therefore overlap with other benign and low-grade malignant tumors. The aim of this article is to report and discuss the differential diagnosis of an aggressive osteoblastoma in the mandible. A 25-year-old male patient reported with pain and asymmetry on the left side of the face since 8 months previously. Radiographic evaluation showed a mixed lesion extending from approximately the lower left premolar to the third molar region. After incisional biopsy, resection with continuity defect was carried out. Microscopic findings showed woven bone and bony trabeculae with varied degrees of mineralization along with sheets of osteoblast cells. Immunohistochemistry showed that p53 and cytokeratin (CK) were negative and ki-67 index was 7%. Postoperative follow-up for 15 months showed no evidence of recurrence

A Direct Investment Method of Closed Two-Piece Hollow Bulb Obturator

Maxillary defects occur due to surgical treatment of benign and malignant tumors, congenital malformation, and trauma. Prosthetic rehabilitation in such patients is influenced by the size and location of the defect. The most common of all intraoral defects are seen in the maxilla, in the form of an opening into the maxillary sinus and nasopharynx. These defects create disabilities in speech, deglutition, and mastication. The prosthesis which closes such an opening and recreates the functional separation of the oral cavity and sinus and nasal cavities is referred to as an obturator. Numerous techniques of hollow bulb fabrication have been mentioned in the literature from time to time. But there are only a few methods for bulb fabrication in two-piece obturator. This technique describes a direct investment method of waxed-up closed hollow bulb two-piece obturator

Perceptions of dental outpatients toward cross-infection control measures in Jabalpur city

Introduction: Infection control practices are crucial and important elements in clinical dentistry as there is an enormous increase in the prevalence of infectious diseases among dental patients. This necessitates the application of recommended procedures for infection control in the dental schools and clinics. Aim: The aim of this study was to assess patients' perception toward the use of protective barriers (such as gloves, face masks, and eye goggles) by working dentists in a private dental teaching school in Jabalpur, Madhya Pradesh (India). Materials and Methods: A cross-sectional descriptive study of a convenient sample of patients visiting the dental school of RDU was conducted in 2015. A structured, close-ended, self-administered questionnaire was distributed among 700 patients and a response rate of 89% was obtained. The questionnaire consisted of a series of questions related to awareness, knowledge, attitude, and perception of patients toward infection control measures. Data analysis included frequency distribution tables. Results: Of 664 patients (298 males and 366 females), 97.7%, 93.5%, and 43.6% of the patients believed that dentist should wear gloves, face masks, and eye goggles, respectively, when treating patients. The majority of them (95.3%) refused to undergo treatment if the dentist is not wearing gloves and face masks. More than two-thirds (73.3%) denied receiving treatment from a dentist, who is not immunized against hepatitis B. Nearly 79.2% of patients refused to attend school if they knew that human immunodeficiency virus (HIV) and hepatitis B virus (HBV) patients treated there. The majority of patients (92.7%, 72.3%, and 23.1%) believed that gloves, facemasks, and eye goggles protect both dentist and patient, respectively. Only 44.9% said that autoclave is the best method of sterilization. A significantly higher knowledge of infection control was observed among the previous dental visitors compared to the first-time visitors (P < 0.05). Conclusions: Patients revealed adequate knowledge toward the use of gloves, face masks, and eye goggles by a dentist. However, their knowledge regarding the use of autoclave was poor. This documentation will serve in planning more effective interventions to enhance public awareness about infection control in dentistry in Jabalpur city, India
