Within the limitations of this study, injection molding techniques exhibited less processing errors as compared to compression molding technique with statistical significance. There was no statistically significant difference in processing errors reported within two injection molding systems.

For a comprehensive dental treatment the interdisciplinary approach has been a trend. Within modern dentistry, periodontics & prosthodontics share an intimate and inseparable relationship in multiple aspects, including treatment plan, procedures execution, outcome achievement and maintenance. By controlling inflammation and preparing sites for proper prosthetic prostheses, periodontists no doubt can provide a solid foundation for successful prosthetic outcomes. On the other hand, prosthodontists could construct proper restorative margin, shapes and contacts that benefit the harmony of periodontium & prosthesis.

Background Because all-ceramic crowns are more aesthetic and biocompatible than metal-ceramic crowns, they have grown in popularity among patients and dentists. Poor finish line layout can result in restoration margin fracturing, hence, finish line arrangement is critical to maintaining the restoration's marginal integrity. The goal of this in-vitro study is to evaluate zirconia's resistance to fracture (Cercon) ceramic restorations with three marginal designs (no finish line, heavy chamfer, and shoulder). This study is important in contributing to the ongoing debate about the optimal finish line design for zirconia restorations. Methodology Three different finish lines, namely, biologically oriented preparation technique (BOPT) with a marginal width of less than 0.3 mm, heavy chamfer with a marginal width of up to 0.3 mm, and shoulder with a marginal width greater than 0.3 mm, were made on 10 extracted maxillary first premolar tooth to make 30 epoxy resin dies on which zirconia (Cercon) coping was done using CAD/CAM technology, and marginal discrepancies were measured using a three-dimensional scanner. All the copings were affixed to their respective dies using GIC luting cement, and fracture resistance was measured using a digital universal testing machine. Results The Kruskal-Wallis test revealed that the mean fracture resistance was more in the heavy chamfer finish line, followed by the no finish line (BOPT) and the shoulder finish line. No statistically significant difference was seen between the no finish line and the heavy chamfer finish line. There was a significant difference between the heavy chamfer and shoulder finish lines (p = 0.004). Conclusions To increase the biomechanical performance of posterior single zirconia restorations, heavy chamfer margins are indicated.

There is a huge difference between a dental clinic and successful dental clinic. Walking through a car or having a long walk on the road, we can see numerous dental clinics surrounding us. Having a tag and degree with the Doctor’s name will not gain the trust of the patients. To be successful, a dental clinic must be equipped with modern amenities and requisite facilities at low and affordable cost. One such clinic of all the clinics in Delhi, that stood out is Dr. Sachdeva Dental Institute, led by Dr. Rajat Sachdeva, perhaps one of the best and affordable dental clinic in terms of quality of treatment given and services provided, equipped with the latest technology at affordable prices. Moreover one of those few dentists in Delhi who follow a holistic approach to dentistry. With people all over the world vouching for their effective treatments at low and affordable cost with best and long term results.

The team at Dr. Sachdeva Dental looks beyond dentistry and delivers customer satisfaction, believing in prioritizing comfort, soothing and relaxing experience to patients. Carry out each and every procedures with utmost diligence. They also provide comprehensive, pain free treatment for all the dental procedures. A multi-specialty dental clinic with the latest equipment and state of the art laboratory that ensure that they deliver you the best. A lot of patients are treated by this clinic and are very happy with the treatments and desired results. Satisfied patients from more than 15 countries.

Aim and objective: The aim and objective of the current study was to evaluate the effectiveness of alveolar distraction osteogenesis technique radiographically for vertical reconstruction of atrophy alveolar ridges in partially edentulous patients.

Materials and Methods: A total of 120 vertical distraction osteogenesis procedures were performed in110 patients. Two panoramic radiographies were performed in all patients, one the day before the beginning of distraction, and one after consolidation period, 18 weeks postoperatively. The radiographic analysis consisted of obtaining the amount of the vertical bone gain in each radiography. For this, we
obtained initially the magnification factor of each panoramic radiography by dividing the real size of the activation rod among the image size of the activation rod. After this, to obtain the VGB, we measured initially the length of the distractonpre activation (LD1), which consisted of the distance between the superior portion of the basal plate and the superior portion of the transport plate, multiplying by the
magnification factor. Then, we measured the length of the distraction postactivation (LD2), using the same method described before, in radiographies performed 12 weeks postoperatively. The vertical bone gain was obtained using the following formula: vertical bone gain = LD2 — LD1. The results were applied to descriptive statistical analysis.Complications were also investigated during all of the treatments.

Results: The mean alveolar distraction achieved in 120 cases was 7.21 (range, 0 to 10.83 mm). According to the region treated, 50.8% were in the posterior mandible (mean vertical bone gain , 4.60 mm, DP: 2.04), 37.68% were in the anterior maxilla (mean vertical bone gain,7.46 mm, DP: 2.28), 7.33% were in the anterior mandible (mean vertical bone gain, 6.73 mm, DP: 2.04), and 4.33% were in the posterior maxilla (mean vertical bone gain, 6.32 mm, DP:2.65).

Conclusions: The Alveolar Distraction Osteogenesis technique was demonstrated to be an effective tool to treat vertical defects of the alveolar ridge with a success rate of 92.64%. Our radiographic analysis seems to be an important tool in verifying the technique as well as planning implant placement after Alveolar Distraction Osteogenesis.
