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.

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.

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.

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.

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.

This case report describes the prosthetic challenges of a patient who underwent a partial hemimandibulectomy and a subsequent free fibula graft after a mucoepidermoid carcinoma resection. This type of osseous reconstruction has several functional as well as esthetic difficulties that must be considered when designing the prosthesis. A thorough case description as well as its follow-up is presented and discussed.

Implantology has become a treatment modality with high acceptance and success rate in the past few decades. Lasers were introduced into the field of clinical dentistry in 1989 with the hope of overcoming some of the drawbacks posed by the conventional dental procedures. The two expanding aspects may be combined to provide the patients with a better clinical experience. Since its first dental application, the use of laser has increased rapidly in the last couple of decades. Their use in implant dentistry has seen an upsurge in the past years. At present, wide varieties of procedures are carried out using lasers. Laser can be classified based on the wavelengths and tissue on which it acts. All available dental laser wavelengths cannot be used in every dental implant situation. The dentist must fully understand the characteristics, merits and demerits, and applicability of the available lasers. The aim of this article is to review the applications of lasers in implant dentistry.

Background: Implantology has now penetrated and become a significant part of mainstream dentistry and is here to stay. Although a number of cost-effective implant system being available in India, implant practice requires in-depth acquaintance and skillful competence. It is the need of the hour that a more structured clinical training including some patient treatment be taught in the undergraduate curriculum. The purpose of the present study was to assess the awareness of implants among interns from various colleges across Ahmedabad city and changes in perception of undergraduates toward implantology over 3 years. Materials and Methods: A questionnaire-based survey was conducted among interns from various dental colleges across Ahmedabad city in 2013 and 2016 to assess the changing trends in knowledge and attitude toward implantology. Results: A total of 600 questionnaires were distributed, 300 each in 2013 and 2016. Nearly 74%–75% of interns were aware about the implant procedure in both the phases of the study. Approximately 80% admitted their inability to perform implant procedure independently due to lack of professional training. Around 50% agreed to introduce and include implantology as a separate subject in BDS. curriculum. Conclusion: The present study suggests that there is a very minimal change in the perceptions and knowledge of dental interns toward implantology over 3 years due to minimal exposure to implant dentistry throughout their BDS. They were not satisfied by the lack of knowledge and welcomed the suggestion of introducing implantology as a separate subject in the BDS curriculum.

This case report demonstrates the neutral zone technique for oral rehabilitation of patient with severe retrognathism, who had a previous implant-supported complete denture with improper relationship between artificial teeth and oral structures. A new mandibular screw-retained implant-supported complete denture was made base-on neutral zone principles to give to the patient a comfortable and functional prosthesis. The nonfunctional position of artificial teeth in complete denture may impair in oral functions such as speaking, swallowing, smiling, as well as loss of denture retention and stability, discomfort, and injuries to oral soft tissues. Neutral zone concept aids to produce complete denture more suitable, once it harmonizes the prosthesis to anatomic structures. In implant-supported complete dentures, retention and stability problems are not a concern. However, in some situations, nonfunctional artificial teeth position causes oral lesions, discomfort, and phonetics problems. Although neutral zone is a technique developed for conventional complete denture, it can be useful in implantology.
