Biological Factors Responsible for Failure of Osseointegration in Oral Implants Review Article Biology and Medicine, 3 (2) Special Issue: 164-170, 2011 eISSN: 09748369, www.biolmedonline.com Biological factors responsible for failure of osseointegration in oral implants *Hadi SA1, Ashfaq N2, Bey A2, Khan S2 1Postgraduate Student, Postgraduate Certificate in Oral Implantology-2010, IGNOU, India. 2Department of Periodontics and Community Dentistry, Dr. Z.A. Dental College and Hospital, A.M.U., Aligarh, India. *Corresponding Author: [email protected] Abstract Oral implantology (implant dentistry) is the science and discipline concerned with the diagnosis, design, insertion, restoration, and/or management of alloplastic or autogenous oral structure to restore the loss of contour, comfort, function, esthetic, speech, and/or health of the partially or completely edentulous patient. Osseointegration, a term coined by Branemark and co-workers in early 1960s, represents a direct connection between bone and implant without interposed soft tissue layers. The aim of the present review is to discuss various factors responsible for loss of oral implants. The factors contributing to failure of osseointegration have been identified as medical status of the patient, smoking, bone quality, bone grafting, irradiation, bacterial contamination, lack of preoperative antibiotics, degree of surgical trauma, and operator experience. Furthermore, it appears that implant surface properties, roughness and premature loading influence the failure pattern. Keywords: Implants; Osseointegration; Failure; Alloplast.

  • Dental Implants Placement of Dental Implants Is a Procedure, Not an American Dental Association (ADA) Recognized Dental Specialty
    Dental Implants Placement of dental implants is a procedure, not an American Dental Association (ADA) recognized Dental Specialty. Dental implants like all dental procedures require dental education and training. Implant therapy is a prosthodontic procedure with radiographic and surgical components. Using a dental implant to replace missing teeth is dictated by individual patient needs as determined by their dentist. An implant is a device approved and regulated by the FDA, which can provide support for a single missing tooth, multiple missing teeth, or all teeth in the mouth. The prosthodontic and the surgical part of implant care can each range from straightforward to complex. A General Dentist who is trained to place and restore implants may be the appropriate practitioner to provide care for dental implant procedures. This will vary depending on an individual clinician’s amount of training and experience. However, the General Dentist should know when care should be referred to a specialist (a Prosthodontist, a Periodontist or an Oral and Maxillofacial Surgeon). Practitioners should not try to provide care beyond their level of competence. Orthodontists may place and use implants to enable enhanced tooth movement. Some Endodontists may place an implant when a tooth can’t be successfully treated using endodontic therapy. Maxillofacial Prosthodontists may place special implants or refer for placement when facial tissues are missing and implants are needed to retain a prosthesis. General Dentists are experienced in restorative procedures, and many have been trained and know requirements for the dental implant restorations they provide. However, if a patient’s implant surgical procedure is beyond the usual practice of a dentist, this part of the care should be referred to another dentist that is competent in placement of implants.

  • Risks and Complications of Orthodontic Miniscrews
    SPECIAL ARTICLE Risks and complications of orthodontic miniscrews Neal D. Kravitza and Budi Kusnotob Chicago, Ill The risks associated with miniscrew placement should be clearly understood by both the clinician and the patient. Complications can arise during miniscrew placement and after orthodontic loading that affect stability and patient safety. A thorough understanding of proper placement technique, bone density and landscape, peri-implant soft- tissue, regional anatomic structures, and patient home care are imperative for optimal patient safety and miniscrew success. The purpose of this article was to review the potential risks and complications of orthodontic miniscrews in regard to insertion, orthodontic loading, peri-implant soft-tissue health, and removal.

  • Parameters of Care for the Specialty of Prosthodontics (2020)
    SUPPLEMENT ARTICLE Parameters of Care for the Specialty of Prosthodontics doi: 10.1111/jopr.13176 PREAMBLE—Third Edition THE PARAMETERS OF CARE continue to stand the test of time and reflect the clinical practice of prosthodontics at the specialty level. The specialty is defined by these parameters, the definition approved by the American Dental Association Commission on Dental Education and Licensure (2001), the American Board of Prosthodontics Certifying Examination process and its popula- tion of diplomates, and the ADA Commission on Dental Accreditation (CODA) Standards for Advanced Education Programs in Prosthodontics. The consistency in these four defining documents represents an active philosophy of patient care, learning, and certification that represents prosthodontics. Changes that have occurred in prosthodontic practice since 2005 required an update to the Parameters of Care for the Specialty of Prosthodontics. Advances in digital technologies have led to new methods in all aspects of care. Advances in the application of dental materials to replace missing teeth and supporting tissues require broadening the scope of care regarding the materials selected for patient treatment needs. Merging traditional prosthodontics with innovation means that new materials, new technology, and new approaches must be integrated within the scope of prosthodontic care, including surgical aspects, especially regarding dental implants. This growth occurred while emphasis continued on interdisciplinary referral, collaboration, and care. The Third Edition of the Parameters of Care for the Specialty of Prosthodontics is another defining moment for prosthodontics and its contributions to clinical practice. An additional seven prosthodontic parameters have been added to reflect the changes in clinical practice and fully support the changes in accreditation standards.

Abstract Purpose: The aim of this retrospective study was to evaluate the feasibility of dual effects of UV photofunctionalized implant, which is placed into piezosurgery-prepared site. Methods: Total 35 cases were subjected to this study. All placed implants were made of commercially pure titanium (grade IV), which were originally surface treated by sandblasting followed by an acid etching. Diameter was ranged from 3.3 mm to 5.0 mm, while length varied from 7.0 mm to 11.5 mm. These original implants were UV photofunctioned and were placed into previously prepared by piezosurgery technique.
