Single Anterior Tooth Replacement By Maryland Bridge With Loop Connector: A Case Report

Restoring a single missing tooth in the mandibular anterior region is often a great concern to the dentist because it requires unnecessary removal of healthy abutment tooth structure. Also because of the drifting of the teeth may reduce the available pontic space or presence of diastema before can result in excessive mesiodistal space which again compromises the aesthetics. When the patients demand more conservative and less invasive treatment options, a combination of Maryland Bridge with a loop connector may be the best alternative option to restore the missing teeth whenever the diastema is present. It is the modification of resin bonded FPD which offers a simple solution when the above dilemma is present. It consists of a loop on the lingual aspect, joining the pontic in the center, and then attaches to the wing retainer on the abutment tooth. This case report provides a straightforward and innovative method for the fabrication of modified resin bonded FPD along with maintaining diastema.

Anterior Single Laminate Veneer Restoration Using CEREC Biogeneric Reference Design Mode: Case Report

The single anterior tooth replacement remains a complex aesthetic challenge for clinicians and technicians in prosthetic dentistry. Maxillary central incisors are the key point of an esthetic smile and should exhibit a high degree of symmetry across the midline. Matching the shape and contours to the adjacent central incisor is the crucial factor to achieve an esthetic result. The CEREC system is the first to use chairside CAD/CAM system, which allows the dentist to provide ceramic restorations in a single appointment without time consuming laboratory procedures.This clinical report demonstrates the effective usage of CEREC system with the biogeneric reference design mode for designing and milling of a laminate veneer restoration in one appointment.Digital images of the preparation and bite registration were captured using an intraoral camera and virtual models were created. With the biogeneric reference design mode of CEREC 3.0 software, the image of the contralateral central incisor is mirrored, positioned over the preparation, and then refined. Among a variety of ceramic blocs available for CEREC system, the restoration was milled from feldspathic ceramic block.

Preservation of Existing Soft‐Tissue Contours in the Transition from a Tooth to an Implant Restoration in the Esthetic Zone Using a Flapless Approach: A Clinical Report

Two-stage placement of a dental implant is a well-established method for restoring a missing anterior tooth; however, replacement of an anterior tooth by using two-stage implant surgery may result in changes in the interdental papilla height and loss of alveolar bone with compromised esthetic results. Alternatively, the use of a one-stage minimally invasive surgical technique followed by immediate provisionalization may facilitate achievement of esthetic and functional success with minimal discomfort and clinical time. This article presents a clinical case with a single anterior tooth replacement, illustrating ridge preservation with healing, delayed implant placement with immediate provisionalization of the implant to support the soft tissue, and a method of recording the soft-tissue contour in the final impression to achieve an optimal esthetic result.
