PURPOSE: To categorize and review complications related to implant dentistry that have resulted in legal actions. MATERIALS AND METHODS: The records of 61 patients (39 women and 22 men) were retrospectively evaluated according to a structured form. Ages ranged from 28 years to 78 years (mean 49 +/- 12 years). The time lag in months between actual damage and legal action ranged from 0 months to 60 months (mean 12.7 months). RESULTS: Implant type, length, width, and locations varied widely and had no impact on the liability report. Half of the lawsuits were filed as a result of actual body damage (loss of sensation, oroantral fistula, life-threatening bleeding); 35% of the lawsuits were filed because of late complications; and 15% were related to immediate complications not leading to actual body damage. The dental consultants acknowledged liability in 41 of 61 cases. The clinician's errors that led to the reported complication were classified as preoperative in 39 of 41 cases. The doctor's attitude was considered positive in 40 cases and negative in 17 cases. DISCUSSION AND CONCLUSIONS: Clinicians should report as soon as possible to their insurance companies to get professional help. The main causes for lawsuits are actual body injury and major disappointment. Practitioners should dedicate a significant part of the entire treatment time to preoperative diagnosis and planning.

PURPOSE: Altered mandibular sensation following implant surgery may result in liability claims. Therefore the authors conducted a retrospective analysis of all liability claims related to persistent altered sensation following placement of mandibular implants reported to the Medical Consultants International (MCI) Company from 1992 to 1999. MATERIALS AND METHODS: Reports related to persistent altered mandibular sensation in 16 patients (12 women and 4 men) who underwent implant surgery in Israel were examined. The MCI files were retrospectively evaluated according to a structured form. The parameters studied included patient age and gender, implant location and length, imaging modality, and the time between actual damage and filing of a claim (ie, letter of demand or lawsuit). RESULTS: The time in months between actual damage and filing of claim ranged from 0 to 60 months (mean 21.5 months). No cases were found involving transient changes in sensation. The female/male ratio was 3:1. Implant length was equal to or longer than 13 mm in 6 of 7 implants placed in the molar region. In the premolar area, nerve injury was evident in 6 of 7 cases where implants shorter than 12 mm were used. CONCLUSIONS: Transient nerve injury rarely results in legal action. Maximum effort should be devoted to accurately determining the appropriate implant length in the mandible. [ABSTRACT FROM AUTHOR]

This clinical report describes the prosthetic management of a patient following total glossectomy and total laryngectomy that severely compromised his oral function, caused facial disfigurement, and limited the patient's quality of life. A feeding aid prosthesis was designed to address the patient's chief complaint of difficulty in feeding and mastication. The prosthesis was designed as an implant-retained overdenture with a lingual metal plate to facilitate food introduction into the oropharynx. This treatment improved mastication, appearance, and the quality of the patient's social life. [ABSTRACT FROM AUTHOR]

OBJECTIVE: The purpose of this prospective study was to compare patient experience of quality of life following surgical endodontic treatment using 2 different techniques: a technique that included the use of a dental operating microscope, root resection with minimal bevel and retrograde preparation with ultrasonic tips, and a traditional technique that included root resection with a 45 degrees bevel and retrograde preparation by bur performed without magnification. STUDY DESIGN: The study consisted of 66 patients referred for surgical endodontic treatment. One operator (I.T.) carried out all treatment. An equal number of patients were assigned to each group. Group 1 was treated by the traditional technique without an operating microscope and Group 2 by a technique using an operating microscope and minimal osteotomy. All patients were given a questionnaire with 15 questions to evaluate their quality of life for 7 days postsurgery. RESULTS: On day 5, patients in Group 1 reported significantly more pain and took significantly more analgesics (P < .05). On days 1 and 2, patients in Group 2 reported significantly more difficulty in mouth opening, mastication, and the ability to speak (P < .05). CONCLUSION: Patients in both groups reported a high incidence of symptoms. The technique using the operating microscope provided significantly less postoperative pain, but more difficulties in mouth opening, mastication, and the ability to speak immediately postoperatively.

Background: The edentulous interforaminal mandibular area is frequently the preferred area for implant placement. Methods: A case of emergency tracheostomy following life-threatening hemorrhage in the floor of the mouth during immediate implant placement in the mandibular canine region is described. The probable cause was bleeding from the sublingual artery or a branch of that artery following implant perforation of the lingual cortex. Results: Healing was uneventful and the patient was released from the hospital after 11 days. Three years later, CT showed a well-osseointegrated implant with a severe buccolingual inclination. Conclusions: It is stressed that short implants (14 mm or less) should be used in the mandibular canine region and that effective treatment of this complication is essential. [ABSTRACT FROM AUTHOR]
