The concept of Osseointegration by Branemark has opened up limitless possibilities and rehabilitation to the extent of involving not only single tooth or multiple teeth but also various developmental deformities and also extensive damage of jaws following injuries and resection of tumors. Dental implants have a long history dating back to prehistoric people where in they have used this technology (Bobbio A. Maya 1973, Tapia JL et al 2002). Dr.Norman Goldberg and Dr.Aaron Gershkoff did research on the use of dental implants and published an article in Dental digest in 1949 and a text book on dental implants in the year 1957. In 1965 Branemark an anatomy professor was the first to place dental implants and later on manufactured implants and drills under the compony named Bofors. Since the introduction of implants in dentistry it has become an esthetic, functional restoration which as a long term predictability (Scheller H 1998). Various factors have been attributed for the success of the implant and impression material and the technique is one of which is considered very crucial and important criteria in the success of fabrication and long lasting of the restoration. A dental impression is a negative imprint of an oral structure used to produce a positive replica of the structure for use as a permanent record or in the production of a dental restoration or prosthesis. Since the accuracy of the impression affects the accuracy of the definitive cast, an accurate impression is essential to fabricate prosthesis with good fit. An inaccurate impression may result in prosthesis misfit, which may lead to mechanical and/or biological complications. A major objective of fabricating implant-supported restorations is the production of super-s... ... middle of paper ... ...me screw and closed tray technique practitioners believe that it is more reliable as visual fastening of the analog to the coping is more accurate and the disadvantage associated with this technique is there are parts to be controlled when fastening and rotational movement of the impression coping when securing the implant analog(Carr AB 1991). Closed tray technique is indicated when the patient has limited inter arch space, gagging tendency or difficult to access the implant in the posterior region (Liou AD et al 1993). This technique uses a single piece impression coping that remains attached intra orally to the implant when the impression is removed. Impression using the closed and open tray technique on the angulated abutments and the number of implants are of little interest as no difference has been seen in between the two techniques (Conrad KJ et al 2007).
This is the process of placing a post into your jawbone. Eventually, implants will allow you to replace teeth you have lost, thus restoring the function and appearance of your teeth.
Amount of the vertical or horizontal augmentation, depicting high quality bone like tissue during reentry, success rate of the dental implants in bone graft area and cloudy histological figures, never can lead to make decision for selecting best treatment for the patients with deficient alveolar ridge, if we do not have detailed map of the recipient bone.

False teeth, which are known today as “dentures”, are bony plates which are installed into a patient’s mouth by means of adhesion to the fleshy mandibular or maxillary arch. Although these are now relatively inexpensive and their requirement is often taken for granted, they have not always been so easy to come by. A look at the history of false teeth shows a pain-staking and quirky evolution:
A subperiosteal implant is often used for patient who has insufficient bone to support and secure full maxillary or mandibular dentures. Subperiosteal implants are made of titanium and are placed to rest on the superior border of the mandibular ridge with bars or post rising above the gingival level. Subperiosteal implant can be placed using either a single step surgical technique or a two stage surgical treatment sequence.
[Flexible dentures are used as a comfortable alternative to the traditional dentures. They do not require metal clasping or mechanisms to hold them in place. Immediate dentures are placed immediately after the teeth removal.]
Osseo-integration has changed various features of restorative dentistry, leading to a substantial improvement in the quality of life for patients who have lost their teeth21. Osseo-integrated dental implants used in rehabilitation of teeth loss, have reliably deliver clinical success, and this type of treatment has a significant positive influence on the psychosocial state of edentulous patients22. Osseo-integrated dental implants are completely fixed in bone, and they do not have a resilient interface. Consequently, only minor movements may occur, which are caused by bone deformation under load3.
To normalize the class III misalignments, the best treatment option is to retrocline mandibular incisors until a positive overlap maintains. The malocclusion was treated with pre-adjusted (0.022 slot) brackets and leveling and alignment using a round 0.014 and 0.016 inch nickel-titanium archwire and a rectangular 0.016 × 0.022 inch nickel-titanium archwire. To align mandibular incisors, 2.5 mm interproximal reduction was performed at 5 anterior contacts (0.5 mm/contact). A rectangular 0.016 x 0.022 inch stainless steel archwire with lingual crown torque on the mandibular incisors was used to retrocline mandibular incisors. To correct the unilateral posterior crossbite, the cross elastics were used to uncross a group of teeth. For finishing, a rectangular 0.019 x 0.025 inch stainless steel archwire was used. After the active treatment phase, wraparound retainer was used for the maxilla and the

Diagnostic tools will be used to develop a customized treatment plan for the patient. Device will be used to gently move the teeth into proper position. There are different types of devices that can be used to gently move the teeth into proper position the teeth alignment and these devices may be fixed or removable. Lingual braces are non-removable an example of removable devices are the invisalign system. The orthodontist will ensure that adequate and continual pressure is applied to the teeth regardless of the device.
Dental implants fuse with the jawbone; thus, providing a sturdy support system for the new artificial teeth. Once a bridge or denture is mounted on implants, the prostheses remains secure, which allows the individual to feel confident while eating and speaking.
if we design a denture whch utilize the presence of the bony undercuts the retention may increase , but we should care on the planing of the the path of insertion in order to benefit from this undercuts without traumatizing the underlying tissue during insertion and removale of the denture . there are two types of path of insertion to improve the retention . first , it is the single path of inserttion which use the labial undercuts , the second , it is the dual path of insertion which use the unilateral undercuts
When the implant is in place, the incision will be closed — typically with stitches (sutures) — and bandaged with skin adhesive and surgical tape.
Natural teeth are ground down to fit in and stabilize the bridge. Implants are set directly into the bone. They do not require damaging other teeth. Implants also prevent any shifting of natural teeth.
Abstract: To aid in retention of prostheses and aesthetic purposes crown lengthening procedures are performed to by allowing placement of restorative margins and proper tooth preparation. Healthy periodontium is a key to a successful prostheses. Different treatment modalities are available for crown lengthening, eg, scalpel gingivectomy, apically displaced flap, ostectomy and lasers.
