Methods to measure implant stability p. 3
Vidya Hiranmayi Kastala
DOI:10.4103/jdi.jdi_7_18  
“Osseointegration” as formulated by Alberktson is crucial for implant survival and success. Osseointegration is a measure of implant stability. Measuring implant stability helps to arrive at decisions as to loading of an implant, allows choice of protocol on a patient to patient basis and provides better case documentation. A successful implant reflects good bone to implant contact and is determined by implant stability both primary and secondary. Implant stability is achieved at two different stages – primary (immediately after implant placement) and secondary (3-4 months after implant placement). Implant stability has been confirmed to affect the process of osseointegration and therefore is essential to understand the methods to measure implant stability and factors influencing. Various methods are developed to assess implant stability which suggests the prognosis of an implant.

Screw versus cemented implant restorations: The decision-making process p. 9
Saj Jivraj
DOI:10.4103/jdi.jdi_7_17  
Improved skills, techniques and materials, case selections and proved designs have witnessed higher rates of success and survivals of osteointegration with dental implants. But prosthesis failures especially mechanical types have been constantly reported. These prostheses have been secured to the integrated implants with cement or screws. Controversies are rife in literature regarding the choice of retention. This review article provides an overview of the various clinical aspects, abutment designs and materials and procedures used, which contribute to selection of type of retention whether screw or cement and highlighting their clinical significance. The clinician can then use these information for optimizing the retention in an given clinical condition and minimize the risk of complications.

Detection of lingual vascular canal by cone-beam computed tomography p. 20

DOI:10.4103/jdi.jdi_17_17  
Objective: The purpose of the present study is to assess the location and size of lingual vascular canal using cone-beam computed tomography (CBCT). Materials and Methods: A retrospective analysis of cone beam CT (CBCT) scan images of 100 patients was done at CBCT centre in Bhopal, India. Patients undergoing CBCT scans for implant placement were included in this study. CBCT machine used was Sirona Orthophos SL (Sirona, Germany) having flat panel detector. Scan parameter adjusted were 70Kv and 8mA, having an exposure time of 14 seconds with voxel size of 8*8mm and spatial resolution of 110μm. The frequency, number, and location of the lingual vascular canals were evaluated. In addition, the exact location of each canal was obtained by measuring the distance to the canal from the inferior border of the mandible. The diameter of the canal was measured midway of the canal wall [Figure 1] and [Figure 2]. Statistical analysis was performed using SPSS software to determine the frequency, location, and number of the canal. Study Design: This study analyzed 100 cbct scans of patients between 20-60 years enrolled at a cbct centre in bhopal, india. this image were acquired using sirona's orthophos SL. two oral and maxillofacial radiologists examined all images to analyzed the location and distance of lingual vascular canal with respect to gender and age. Results: About 100 patients (male = 49 and female = 51) demonstrated the presence of lingual vascular channels (LVC) with only one patient showing three canals. Hence, the maximum number of single and double lingual vascular canal was present in female patients. The mean distance from the inferior border of mandible was 9.39 ± 3.28 mm in males. There was no significant difference regarding the location of the lingual vascular canal and its presence and absence. Gender-wise distribution of lingual vascular canal in male patient was 49, and in female patients, it was 51. Conclusion: CBCT provides adequate information regarding number and size of lingual vascular canal, which is an important anatomical structure in mandibular anterior region.

CASE REPORTS Top

Immediate implant placement and loading using fractured lateral incisor and surgirest template p. 25
Cosimo Petrucci, Michael Zaninovich
DOI:10.4103/jdi.jdi_2_18  
This clinical case report presents a novel laboratory technique to place an angulated implant fixture and fabricate an immediate provisional-fixed implant prosthesis using the patient's own extracted tooth. Preservation of the local hard and soft dental tissues with the immediate prosthesis assists predictability when the clinical situation permits.

A novel implant designed to improve mechanical bone adaptation p. 31
Amos Ben-Yehouda
DOI:10.4103/jdi.jdi_9_18  
Research shows an exaggerated bone loss adjacent to installed implants during the healing period. This phenomenon may continue later along the years in a slower rate. Sometimes, there is even an acceleration of the phenomenon during the years. The presented implant was designed to restore short-term bone loss caused during the healing phase and to slow and even prevent long-term bone loss. The result is achieved by emitting at the bone, mainly, compressive stress vectors that are essential for improved mechanical bone adaptation, including organization of bone into load-bearing type and modeling of the bone by enlarging its volume. This case report shows how a nonfunctional bone architecture turns into a load-bearing type and how initial bone loss may be restored after implant loading.

Fabricating a stent for accurate and reproducible measurement of peri-implant pocket depth p. 34
Himanshi Aggarwal, Saumyendra Vikram Singh, Kopal Goel, Rani Ranabhatt
DOI:10.4103/jdi.jdi_10_18  
Pocket probing around dental implants is an important diagnostic procedure for the assessment of peri-implant status and evaluation of periodontal therapy. Conventionally, probing is done arbitrarily in the center of four aspects (mesial, distal, facial, and lingual/palatal) of implant without removal of the prosthesis. The prosthesis design leads to a steep convergence angle of probe insertion or possible penetration of peri-implant tissues which leads to incorrect measurement. The present technique describes a vacuum formed polyvinyl chloride stent that allows peri-implant pocket depth measurements to be performed repeatedly and reproducibly at pre- and post-rehabilitative recall appointments.

Implant and prosthetic planning using cone beam computed tomography and radiographic markers for full mouth-fixed implant-supported prosthesis: A technique p. 37
Tushar Ranjan, Makam Gangaiah, Avadhesh K Chaubey, Isha Wadhwa, Kunal Nischal
DOI:10.4103/jdi.jdi_5_18  
A fixed implant-supported full mouth prosthesis has been a routine treatment plan for completely edentulous patients. A systematic planning is must for successful implant placement and restoration. This article describes a technique to form a bridge between implant planning and execution of the plan using radiographic markers and cone beam computed tomography.
