Abstract

Aim: The aim of the study is to assess treatment success of teeth loss patients with class III skeletal malocclusion through a multidisciplinary approach, including orthognathic surgery and implant prosthetic rehabilitation. Materials and methods: The present retrospective study investigated the 5-year clinical treatments outcomes 16 patients with class III malocclusion and teeth loss. Clinical, laboratory, radiological methods were used in the examination of patients. Surgical stage included sagittal bilateral osteotomy of the lower jaw and reposition it back (Le Fort I osteotomy). 7–8 months after the orthognathic surgery 132 implants were inserted. After 2 to 4 months of submerged healing period patients had received implant-fixed prostheses. Results: No serious intraoperative or immediate postoperative complications were noted. At the control examination after 6 months after surgery, from an X-ray examination we did not observe any clinical or radiological signs of inflammation in the area of osteotomy sites and titanium mini-plates. Success rate of implants after 5 years was 96.2%. Conclusion: After orthognathic surgery and dental implant prosthetic rehabilitation, the masticatory function, esthetics of the facial profile, and occlusion were improved. Patients expressed satisfaction with the result of treatment and improved quality of life.

A Microleakage Evaluation of Two Generations of Bonding Agents Using a Novel Fluid Filtration Model

[Year:2020] [Month:January-March] [Volume:10] [Number:1] [Pages:5] [Pages No:21 - 25]

Abstract

Aim: The aim of the study was to evaluate the microleakage between two different generations of bonding agents using fluid filtration model. Materials and methods: In total, 60 human extracted mandibular molars were used in the study. The samples were divided into three groups, group I—Adper Scotchbond primer and adhesive, group II—Single Bond Universal adhesive, and group III—control group. All the samples were restored and stored in distilled water for 24 hours followed by thermocycling in water bath for 1,000 cycles between 5 ± 2°C and 55 ± 2°C, for dwell time of 30 seconds and transfer time of 10 seconds. The samples were then tested for leakage under fluid filtration model. Results: There was a statistically significant difference between the leakage in between the two groups. The difference was found to be statistically significant (p < 0.05). Single bond group showed better adhesion and less leakage compared to the Adper Scotchbond primer and adhesive. Conclusion: Single Bond Universal adhesive (3M) showed the least amount of microleakage when compared to Adper Single Bond 2 and Adper Scotchbond primer and adhesive. Fluid filtration model was successfully constructed and worked efficiently and can be considered as one of the ideal methods for evaluation of microleakage.

An Evaluative In Vitro Study of the Effect of the Three Commercially Available Denture Cleansers on Physical Properties of Heat-cured Resin

[Year:2020] [Month:January-March] [Volume:10] [Number:1] [Pages:6] [Pages No:26 - 31]

Keywords: Color stability, Denture bases, Denture cleansers, Flexural strength, Surface roughness

Abstract

Aim: This study aims to evaluate and compare the effect of using three commercially available denture cleansers on surface color, surface roughness, and flexural strength of heat-cured resin. Materials and methods: A total of 80 rectangular heat-cured acrylic specimens were fabricated and all were immersed in denture cleansers over a period of 6 days in which 30 immersions were performed. Then the physical properties of the heat-cured resin were tested using portable colorimeter, universal testing machine, and surface analyzer. The paired t test was done to compare the before and after immersion values for color, surface roughness, and flexural strength in denture cleansers. The post hoc test was performed to make multiple comparison among different groups. Results: All heat-cured resin bases presented with changes in color, surface roughness, and flexural strength to some extent when immersed in all the three denture cleansers. The values of change in color, surface roughness, and flexural strength were higher when immersed in Clinsodent as compared to all other groups. Conclusion: The changes observed in color and surface roughness of all resins samples were within the clinically accepted range while significant decrease in flexural strength was seen on immersion in all three denture cleansers; least change was observed with the Secure denture cleanser.

Simple Estimation of Movement of the Distal Segment Separately at the Right and Left Vertical Osteotomy Lines in Sagittal Split Ramus Osteotomy

[Year:2020] [Month:January-March] [Volume:10] [Number:1] [Pages:3] [Pages No:32 - 34]

Abstract

To estimate the linear and rotational movement of the distal segment in sagittal split ramus osteotomy on the right and left sides, we developed a simple method using the common dental materials. This technique was based on the double-split cast method. Two removable intermediate components were used, one for the original mandibular positioning and the other for the postoperative one. In the original position, a wire was fixed at the buccal side of the first molar of the cast model, corresponding to the vertical osteotomy line of the sagittal split ramus osteotomy on the right and left sides. Another wire was fixed at the base of the articulator on each side, so that the upper portion of the wire is adjacently parallel to the one attached to the cast model. The original intermediate component was replaced with the postoperative component, creating a gap between the wires. The gaps reflect the required movement of the distal segment on each side, which often differs between the right and left.

Twin-occlusion Prosthesis in a Class III Hemimandibulectomy Patient

[Year:2020] [Month:January-March] [Volume:10] [Number:1] [Pages:4] [Pages No:35 - 38]

Abstract

Discontinuity of the mandible results in deviation of remaining mandible toward the resected side. There are many ways of rehabilitating a hemimandibulectomy patient. The patient described in this case report presented with early squamous cell carcinoma of left mandibular alveolus underwent class III hemimandibulectomy and reported to the department of prosthodontics for rehabilitation of the defect as he faced difficulties in mastication and was also concerned about esthetics. This case report describes a technique for rehabilitating a hemimandibulectomy with complete dentures along with twin occlusion.

Computer-aided Design and Computer-aided Manufacturing Restorations with Minimal Invasive Approaches

[Year:2020] [Month:January-March] [Volume:10] [Number:1] [Pages:5] [Pages No:39 - 43]

Keywords: All-ceramic restorations, CAD/CAM, Minimal invasive

PDF  |  DOI: 10.5005/jp-journals-10019-1258  |  Open Access |  How to cite  | 

Abstract

Implant-supported crowns, full-coverage fixed dental prostheses and inlay-retained fixed partial prostheses are treatment methods typically used for the rehabilitation of a single missing posterior tooth. With the increasing emphasis on conservative treatment in dentistry, inlay-retained adhesive restorations are becoming popular. With the progress of computer-aided design and computer-aided manufacturing (CAD/CAM) technology, ceramic restorations in the posterior region can be fabricated with sufficient esthetic and mechanical properties. This case report illustrates an alternative approach to the rehabilitation of narrow edentulous spaces with ceramic materials by CAD/CAM technique with minimally invasive approaches.
