Medical Contraindications to Dental Implant therapy: A Review
Proper case selection is needed for a successful implant therapy. For a successful implant case, an appropriate healing response is required. Not all edentulous patients are candidates for implant therapy. Absolute medical contraindications exist and must be adhered to. In order to avoid any infection, implant failure, or even patient death. But then there are conditions, if stabilized, they do not interfere with healing; those are relative contraindications to elective oral surgery. The careful practitioner understands the nature of a number of diseases assess evidence regarding implant therapy in such patients and picks his or her cases based on this knowledge. It is an informed choice that we make, and if we choose properly, predictability results.

Perio-Prostho Interrelationship:A Review
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.

Comparing the Effect of Gingival Retraction Method Using Magic Foam Cord and Expasyl Paste
Aim – The purpose of this study was to evaluate and compare the effect of two cordless retraction techniques and their influence on gingiva.


Material and Methods – Participants (n=40) with healthy gingival conditions were recruited- an expanding polyvinyl material(Magic foam cord), a paste like material (Expasyl) were applied in the posterior tooth of the subjects. Following impressions casts was measured for the gingival retraction with 3D scanner. Gingival health was assessed after one week and the collected data was tabulated and subjected to statstical analysis.


Result- Mean gingival displacement obtained by the Expasyl paste was more effective as compared to the magic foam cord i.e, 0.30mm and 0.23mm respectively and the obtained “p” value was p<0.001 which was extremely significant.


Conclusions – Within the limitations of this study the conclusions were made that both the retraction agents were convenient to use, painless and they achieved the adequate gingival retraction and they wont result in any gingival inflammation and gingival recession.

Comparative Effect of No Finish Line, Heavy Chamfer, and Shoulder Marginal Designs on the Fracture Resistance of Zirconia (Cercon) ceramic restoration: An In Vitro Study
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.

Mandibular Flexure and Crestal Bone Stress Distribution on an Implant Supported Fixed Full Arch Mandibular Prosthesis: Finite Element Analysis in Three Dimensions.
Aim

This study's objective was to assess and analyze, using 3D Finite Element Analysis, the impact of four mandibular complete arch superstructures on the distribution of stress in the crestal bone during mandibular flexure.

Materials and methods

Four Finite element models of the mandible with different implant-retained framework designs have been developed. Three of these models had six axial implants placed at intervals of 11.8 mm, 18.8 mm and 25.8 mm from the midline, respectively. One model had two tilted implants and four axial implants splinted with a single piece of framework at intervals of 8.4 mm, 13.4 mm and 18.4 mm from the midline. For analyzing the stress distribution, the finished product was transferred to ANSYS R 18.1 software (Sirsa, Haryana, India) for finite element simulation, the models were constructed, the ends were restrained, and bilateral vertical loads of 50N, 100N and 150N were applied to the distal part of the framework.

Results

Bilateral loads were applied to each of the four 3D FEM and after assessment of Von Mises Stress and Total Deformation, a finding was made that the model with six axial implants supported by a single piece of framework underwent the highest total deformation and the model with four axial implants and two implants with distal tilts displayed most significant Von Mises stress.

Conclusion

Within the constraints of this 3D FEA, it was determined that mandibular flexure and peri-implant bone stress were affected by the way the framework is divided and the nature of mandibular movement. The three types of frames with the least bone stress are demonstrated by the mandibular deformation that results from two-piece frameworks on axial implants. Regardless of the number of implants, the single framework splinted with six implants shows a flexure in mandible with the highest bone stress around the implant irrespective of the angulation of the implant.

Clinical significance

When it comes to edentulous jaws, reducing stress in implant-supported restorative systems at varying degrees of the bone and implant interfaces and superstructures of prosthetics is one of the fundamental goals of implant treatment. A framework with proper design and a low modulus of elasticity reduces mechanical risk. Additionally, a larger number of implants helps to prevent cantilevers and spacing between the implants.

Alveolar Distraction Osteogenesis Analysis by Radiographic Mean for Vertical Reconstruction Of Alveolar Ridge: A Novel Research Approach.
Author : Dr. Naqoosh Haidry, Dr. Ritesh Raj, Dr.Brijesh Byrappa, Dr. Amit Kumar, Dr. Manish Kumar, Dr. Anshu Prakash

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.

A Comparative Study of the Effect of Primary and Secondary Closure Technique Following Removal of Impacted Mandibular Third Molars
Author : Naqoosh Haidry, Ritesh Raj, Sandeep Kashyap, Brijesh Byrappa, Amit Kumar, Ankur Singh

Introduction: Surgical removal of the impacted mandibular
third molar is one of the most frequently performed surgical
procedures in oral and maxillofacial surgery. The purpose of
this study was to compare the primary and secondary wound
closure after surgical removal of impacted mandibular third
molars by evaluating the extent of facial swelling, the severity
of pain and degree of trismus.

Material and Methods: A prospective, randomized,
clinical trial was conducted in 80 patients. The patients were
randomly divided into two groups of 40 each. In Group 1:
patients underwent primary closure of the wound and in
Group 2: patients underwent secondary closure of the wound.
Postoperative pain, swelling, and trismus were evaluated on
the 2nd and 7th day postoperatively.

Results: Statistically significant difference was observed for
facial swelling and trismus on 2nd postoperative days between
both groups. Postoperative pain was less in the secondary
closure group.

Conclusion: From the outcome of the above study we can
conclude that the secondary wound closure technique has a
significant advantage over primary wound closure concerning
swelling and trismus.
