Implant Overdenture Research Paper

Treating the completely edentulous upper jaw with fixed implant-supported teeth has always been difficult, especially if it is suffering from moderate to severe bone loss. One procedure that has long been available is the use of bone transplant or bone grafting, usually from the patient’s skull, hip, jaw or skin, to supply the missing bone in the upper jaw. Because this requires a second

So here we go for an advanced technique of implanting which provides a more secure and stable denture. Most people prefer to get replaced with the permanent teeth. For those people, we move on with their desire using a technique called as a hybrid denture. It consists of dentures that are fixed onto implants with a full set of high-quality prosthetics to replace full rows of teeth.

A bridge is considered radical treatment as adjacent tooth structure must be drastically reduced in this process. The bridge has been regarded as the standard of care for some time in the replacement of single and multiple missing teeth. However, in order to obtain optimal functional and aesthetic results for full-veneer bridges, a significant reduction in the amount of tooth structure is necessary, occasionally predisposing to endodontic, periodontal, and structural complications. The abutment teeth often become carious and thus have an increased rate of those individuals needing a root canal procedure. If one of the abutment teeth are lost a longer span bridge would be required. The implant procedure is more conservative and has a better prognosis. Implants have a high rate of success, do not require procedures on adjacent teeth and are not susceptible to caries.

WookHeo, Dong-SeokNahm, and Seung-HakBaek (2007)32performed study to compare the amount of anchorage loss of the maxillary posterior teeth and amountof retraction of the maxillary anterior teeth between en masse retraction and two-step retraction of the anterior teeth.30 female adult patients with Class I malocclusion and lip protrusion were included in the study. The sample was subdivided into group 1 (en masse retraction) and group 2 (two-step retraction). Lateral cephalograms were taken before (T1) and after treatment (T2). Nine skeletal and 10 anchorage variables were measured, and independent t-test was used for statistical analysis.The amount of horizontal retraction of the maxillary anterior teeth was not different between the two groups, there was mild labial movement of the root apices of the upper incisors in group 2 at T2. No significant difference in the degree of anchorage loss of the maxillary posterior teeth was observed between the two groups. Bodily and mesial movements of the upper molars occurred in both groups. A 4 mm of the retraction of the upper incisal edges resulted from 1 mm of anchorage loss in the upper molars in both groups.

The implant-retained overdenture is a treatment option for edentulous patients in the following situations: poorly retained and unstable mandibular dentures, poor bone quality or insufficient available bone to accommodate 4 or more implants, as the original Branemark protocol suggests, and to aid patients with financial constraints. When compared to the fixed implant-supported restoration, the removable implant-retained overdenture offers several advantages including enhanced access for oral hygiene, easy modification of prosthesis base, and the provision of a labial flange to improve esthetics in situations of unfavorable jaw relationship.

In a study of 34 patients aged 75 years or over who depended on assistance for daily living activities, patients were randomly assigned to receive two mandibular implants to support an overdenture or a relined conventional mandibular denture. In the patients who received the mandibular implant overdenture treatment, an increased oral health-related quality of life was reported; however, chewing efficiency was no different between the groups. The insertion of the mandibular implant overdenture was noted as problematic for some patients and their caregivers due to the nature of the Locator attachments, and in two cases the attachments were replaced by attachments that permitted easier insertion . This is an important consideration for

Endosseous dental implants have made a tremendous breakthrough in dentistry revolutionizing the restorative possibilities since early 1970's1. They provide an impressive, idealized(both in function and appearance ), and durable restorative results for a variety of Prosthodontic situations ranging from single teeth, crowns,bridges and complete dentures2,3,4,5.

Implant procedures has become more common practice. With proper selection of patients and treatment planning, using dental implants to replace missing teeth can provide long lasting functional and aesthetic restorations. However, when poorly executed, many problems can arise. Failure to integrate is usually not as difficult to manage as an improperly positioned implant. When an implant fails, proper treatment plan should be explained all the relevant variable. Patients should be informed about all the possible treatment modalities after implant failure and give their consent to the most appropriate treatment option for them. The key to preventing these types of failures is proper treatment planning.

Recent surveys about retention procedures, done by (Renkema, et al. 2009) and (Lai, et al. 2014), showed some similarities among orthodontists practicing in various countries, such as a frequent use of fixed retainers on mandibular teeth, and an increased popularity of removable vacuum-formed retainers..

The orthopedic implants are considered universally applicable to all skeletons,irrespective of the differences among various ethnic groups. Although different size of same design generally are available from manufactures, there is little evidence that ethnic morphologic difference are taken into account in orthopedic implant design.63,64 This universal application may not cause major clinical problems in implants that are applied externally to the skeleton;however, problems do arise with implants that are applied internally to skeleton. This becomes obvious in Intra medullary fixation of fracture and hip prosthesis,where linear and angular configuration has to be considered 61,62,64 The implant device and prosthesis designed for

Many patiеnts choosе implants to rеplacе a singlе tooth, sеvеral tееth, or to support a full sеt of dеnturеs. Implants arе posts that arе surgically placеd in thе uppеr or lowеr jaw, whеrе thеy function as a sturdy anchor for rеplacеmеnt tееth. Thеy arе madе of titanium (a strong, lightwеight mеtal) and othеr matеrials that arе accеptеd by thе human body. Most patiеnts find that an implant is sеcurе and stablе—a good rеplacеmеnt for thеir own tooth. Howеvеr, implants arе not an option for еvеryonе. Bеcausе implants rеquirе surgеry, patiеnts should bе in good hеalth ovеrall. Patiеnts еithеr must havе adеquatе bonе to support thе implant, or bе ablе to havе surgеry to build up thе arеa nееding thе implant. Patiеnts also should bе rеady to commit to a daily oral carе routinе and to rеgular dеntal visits.

Correcting a deep overbite is a very common goal in orthodontics, therefore the majority of patients require a control of the vertical overlap during the retention phase. The vertical overbite can be maintained using a maxillary retainer with an anterior biteplate incorporated within it, so that when the bite starts to deepen, the base plate contacts the lower anterior teeth and prevents the bite deepening (Figure 2.9). The retainer should not separate the posterior teeth. The patient should not stop wearing his/her retainer, but he/she may wear it only at night, after stability in other regards has been achieved, because the vertical growth continues into the late teen (Proffit 2007). Growth pattern might be the most influential factor that

In the past two decades, implant-supported overdenture has improved the quality of life of edentulous patients. With this type of treatment patients are freed of the problems associated with common full dentures such as reduced retention, stability and mastication power which occurs over time and gradually resorption of jaw bone.

Advances in dentistry have been revolutionary in the last several decades. According to the literature, the effects of an aging population contribute to the need for more and more prosthetic work in dentistry, notably because of tooth loss. The push towards dental implant prosthetics comes from this aging population losing more teeth, consequences of fixed prosthesis failure, anatomical consequences, poor performance of removable prosthesis, consequences of partial dentures, and even the psychological aspects of tooth loss and the needs of a changing social stigma regarding dental issues (Misch). Unfortunately, while an implant-supported restoration tends to offer a predictable treatment for tooth replacement, failures do occur. These failures sometimes negatively impact the physical and psychological situation for the patient; involving further cost and additional procedures. For the dental professional, failures jeopardize the ability to successfully treat the desired issue, from both a medical and an aesthetic point of view, as well as confidence in the dental provider and treatment option (Levin).

A removable partial denture is a component of prosthodontics that acts as an artificial restoration replacing one or more missing teeth (but not all the teeth) and their supporting structures. The main objective of removable partial dentures is the reconstruction of the proper oral function including mastication, esthetics, speech and patients’ comfort. Other objectives include maintenance of health of the teeth and oral structures (as the alveolar bone) and to get rid of any oral diseases. Advantages of a removable partial denture include providing support to teeth having periodontal diseases and collapsed structures as cheeks and lips. In Addition, it maintains the vertical dimension of teeth thus preventing TMJ problems. Moreover, it prevents over-eruption, tooth drifting and alteration of the remaining teeth. Added to that, it achieves better oral hygiene by preventing food stagnation in the empty space of lost teeth and can be easily adjusted and repaired. Also, it is cheaper and requires fewer procedures intra-orally than fixed partial dentures. On the other hand, some of the drawbacks of a removable partial denture involve poor oral hygiene if not properly cleaned, affecting the remaining teeth negatively and limiting the oral comfort
