Rehabilitation of a partially dentate postmaxillectomy patient using a novel approach is presented in this report. The patient was referred to our practice by the oral and maxillofacial surgery department of the local general hospital for the evaluation and prosthetic treatment planning. He had undergone biopsy for a lesion located in the right quadrant of his maxilla and was scheduled for a hemimaxillectomy for removal of a squamous cell carcinoma. A surgical obturator was prepared for placement at the time of ablative surgery...

Context: Determination of horizontal condylar guidance (HCG) by various clinical and radiographic methods was performed by several investigators. If a correlation between HCG values using lateral radiographic tracing and protrusive interocclusal records can be established, the necessity of performing elaborate recording procedures can be eliminated. Aims: The aim of this study is to evaluate and to compare the correlation between HCG values in edentulous people using the protrusive interocclusal records mounted on a semi-adjustable articulator with the manual tracing of panoramic radiograph and lateral cephalogram...

Aim: The purpose of this study was to compare the wettability of saliva, a saliva substitute, and distilled water to three denture base materials. Materials and Methods: Thirty specimens of each denture base material: Heat cure polymethylmethacrylate (DPI heat cure), high-impact polymethylmethacrylate (Trevalon HI), and nylon (Valplast) were fabricated. The specimens of each denture base material were divided into three groups of ten specimens. The advancing and receding contact angles of three media: a commercially available carboxymethylcellulose-based saliva substitute (WET MOUTH), human whole saliva, and distilled water, with each denture base material were determined using a goniometer...

Background: Prosthesis misfit plays an important role in complications such as occlusal and abutment screw loosening and fracture in implant restorations. Reproducing the intraoral relationship of implants through impression procedures is the first step in achieving an accurate, passively fitting prosthesis to ensure maximum accuracy. Hence, splinting of multiple implants with most accurate material may be a valid option. Context: The results of splinting multiple implants are always inconsistent, and there is limited literature available to compare the accuracy of impression techniques as well as materials...

Purpose: Since the services of a qualified practitioner are not easily accessible to the vast majority of the population, the gap is filled literally at the roadside by the ubiquitous unqualified practitioner. The present article emphasizes on the outcome of prosthesis which the quacks deliver for the replacement of natural teeth. Materials and Methods: In the present study, we had explored the reason why people visit these quacks, the complications which they face after using fixed dentures delivered by the quack and some solutions to tackle quackery...

Statement of Problem: Various osteotomy modalities seem to have an impact on the primary and secondary stability of the dental implant. The available literature lacks the comparison of various available osteotomy modalities used for the dental implant placement and its effects on the initial surgical bone removal. Purpose: The purpose of this study is to compare and evaluate the osteotomy sites created using standard drill, bone trephine, and alveolar expanders for dental implant surgery...

Background: Complaints with complete dentures is a common and expected phenomenon. However the type and character of complaint varies between population and is influenced by the socio economic condition, prevalent dental awareness etc. This study attempts to find the most common complaints with complete dentures, their causes and also presents a classification of the same. Method: A cross-sectional analytical study was conducted by performing a survey on a sample of population over an 18 month period utilizing a customized questionnaire...

Aim: The aim of this study was to compare the adhesion of glass-ceramic overlays to tooth structure, under the effect of shear forces, using different bonding systems. Materials and Methods: Thirty healthy lower third molars were selected and randomly allocated into three groups ( n = 10). Group 1: overlays bonded to tooth structure using Panavia V5 with immediate dentin sealing (IDS); Group 2: overlays bonded using Panavia V5 without IDS; and Group 3: overlays bonded using heated composite combined with a bonding agent with IDS...

Purpose: This systematic review aimed to evaluate retention failures in cement- and screw-retained fixed restorations on dental implants in partially edentulous arches. Methods: The relevant articles were retrieved from MEDLINE (PubMed), Cochrane Library, and EBSCO electronic databases for articles published from January 1995 to January 2016 and were restricted to randomized controlled trials and retrospective and prospective studies on human subjects that were reported in English...

Primary stability in dental implants is an essential factor for achieving successful osseointegration. Surgical procedure and bone quality are among the most common factors that affect primary stability. It is also crucial to achieve high-insertion torque which is important for obtaining primary stability. Maintaining sufficient bone bulk and density is essential to achieve necessary bone-to-implant contact for obtaining a biomechanically stable implant. A new concept for osteotomy called osseodensification (OD) has been at the forefront of changes in surgical site preparation in implantology...

Screw loosening is the most common factor associated with dental implant failure. One of the major cause for screw loosening is the "loss of preload". Several factors including screw geometry, material properties particularly stiffness, surface texture and condition of mating surfaces, degree of lubrication, rate of tightening, integrity of joint etc. Objective: This review analyses the factors that are responsible for the loss of preload. Material and Methods: Screw geometry, Implant- Abutment Connection type (external hexagon platform, morse taper), Material properties viz Stiffness, Resilience, Materials viz gold, titanium, titanium alloy, Surface texture of the abutment screw, Condition of mating surfaces, Lubrication, Torque value, Rate of tightening (10, 20, 35N and retorque after 10mins) are taken into consideration in this study...

Myogenous temporomandibular disorder (TMD) is the most common type of nonodontogenic pain. The diagnosis is often elusive since diagnosing such conditions often requires a more comprehensive patient assessment. At present, there is no simple one-step diagnostic test to help render a definitive diagnosis of myogenous TMD pain. The twin-block injection can serve as a diagnostic aid to facilitate diagnosis of such myogenous TMD. The twin-block injection blocks the innervation to both the temporalis and masseter muscles, the two most common sources of referred pain to the teeth...

Background: Residual ridge resorption is crucial sequelae of tooth loss. Complete dentures are the most common way of rehabilitating edentulous patients. However, with continuing residual ridge resorption, dentures tend to become loose and unstable causing discomfort, chewing disability, and speech problems. Denture relining is an economical means of improving a denture's stability and retention. An understanding of the clinical indications and limitations of these materials and procedures is crucial for clinical success...

Background: The presence of the dental papilla is critical to achieve esthetics in a single tooth implant restoration. Aim: The purpose of this study was to determine if there were differences in the papilla fill between implant and teeth comparing immediate implant placement and provisionalised single tooth implant restorations with delayed implant placement and provisionalised single tooth implant restorations. The papilla fill in these two groups was evaluated using the Jemt papilla index...

Statement of Problem: In clinical situations, short implant abutments create lack of retention with overlying cemented prosthesis. Aims: The aim of this study is to evaluate the impact of different surface treatments on the retention of implant-supported cement-retained bridge with short implant abutments. Materials and Methods: Six straight Adin implant abutments of similar sizes (3 mm diameter × 3 mm height) were selected. All were divided into three groups ( n = 2): with circumferential grooves and sandblasting (G + SB), with a circumferential groove and bur modification (G + B) and third one taken as control...
