Retrospective on Treating Periimplantitis

1st European Workshop on Periodontology in 1994 defined Periimplantitis as the inflammatory reactions in the hard and soft tissues, with loss of supporting bone, surrounding a dental implant exposed to the oral environment. A successful dental implant is defined as immobile when tested clinically. Vertical bone loss is less than 0.2 mm annually following implant first year of service, as well as, the absence of pain, infection, neuropathies, and parasthesia .
There are a number of reasons for an implant to fail. They include
a) Implant overstressed due to hyper-occlusion
b) Apical pathology from adjacent tooth
c) Retained cement on cementation of prosthesis
d) Residual bacteria left from either endodontic, periodontal pathology

The aim of this article is to present most common causes of periimplantitis and to show treatment for each of these. Somecauses can be prevented by careful use sound clinical skills and others byprevention of chronic inflammation, recognizing early signs of soft tissue inflammation around a dental implant. This article will focus on each of these failures and provides a treatment protocol or prevention for these problems.
Periimplantitis
Case Studies: Overstressed implants:
Over functioning on implants is a problem. Either due to overloading on completion of the implant case, or due to changes in restorations opposing an implant can cause this scenario. The first case that exhibits this is a female that had a single implant placed distally that was designed to take compressive forces on a free-end-saddled partial. The patient was to return back to her referring dentist to reline the distal saddle. The patient did not do as instructed, and after 3 years the patient presented a buccal fistula.

Harvesting Free Palatal Masticatory Mucosal Graft Using 3a Mucotome

Image
The technique of free autogenous gingival grafting (FGG) has undergone little modification since its introduction by Bjorn in Scandinavia in 1963 and by King and Pennel inthe United States in 1964. The technique is widely used to treat a variety of mucogingival problems such as insufficient or lack of attached gingiva, the presence of high frenum attachments, shallow fornix and denuded roots following gingival recession.  FGG can be procured from donor site using scalpels, gingivectomy knife or palatal shaving knife (Paquette knife). The donor site is frequently the palate, although the use of edentulous ridge areas, tuberosity and attached gingiva has also been described. Scalpel is most commonly used and conventional method for procuring gingival auto grafts. Gingivectomy knife, although not commonly used, also works on similar principle. Since the scalpel blade is straight and stiff and the palate is curved, repeated incisions to release the graft from underlying connecti

Dental Ailments may be risky for Cardiac Patients

Image
Patients that are suffering from cardiac t=disorders are susceptible to physical and mental stress. Dental ailments add to the stress further as these patients are unable to cope with the pain due to cardiac disorders. These patients may encounter medical emergencies in case of dental disorders and they may demand multi disciplinary approach to achieve the success. Additionally, the results of cardiac surgery may suffer if the oral cavity is not maintained well since there is always a fear of infection affecting the heart from the oral cavity. Hence, the cardiac surgeon has to refer surgical patients to a dentist for oral prophylaxis and to treat any oral infections before cardiac surgery to prevent infective endocarditis. PDF LINK

Indications for Orthognathic Surgery

Image
Orthognathic surgery (OS) is a surgical intervention that alters relationships of the jaws and dental arches. The treatment involves a combination of orthodontics and maxillofacial surgery.  Orthognathic Surgery It is used to correct dentofacial deformities that cannot be treated with acceptable results by conventional orthodontics. The first description of a surgical intervention to correct a malocclusion was by Hullihen in 1849. The most frequently used surgical procedures for correcting the relationship of the jaws are Le Fort I osteotomy and sagittal ramus split osteotomy. Also often used are vertical ramus osteotomy, inverted L osteotomy, and variations and combinations of the above. Read More>>>>>>
