Summary
This review identifies dental implant complications, finding higher implant loss with overdentures and in the maxilla. Factors like short implants and poor bone quality increase loss, with varied timing and types of complications reported.
Area of Science:
- Dental Implantology
- Oral Surgery
- Prosthodontics
Background:
- A comprehensive review identifying complications in clinical dental implant studies is lacking.
- Existing literature lacks a consolidated understanding of reported dental implant complications.
Purpose of the Study:
- To identify and categorize reported complications in dental implant studies.
- To quantify the frequency of various dental implant complications.
Main Methods:
- Systematic evaluation of clinical studies published between 1981 and 1997.
- Analysis of implant loss based on prosthesis type, arch, time, implant length, and bone quality.
Main Results:
- Higher implant loss observed with overdentures and in the maxilla compared to the mandible.
- Implant loss correlated with shorter implant length and poorer bone quality.
- Complications encompassed surgical (e.g., neurosensory disturbance), peri-implant soft tissue (e.g., gingival inflammation), and mechanical issues (e.g., screw loosening).
Conclusions:
- While the literature contains data on implant complications, study design variations limit comprehensive analysis.
- Standardized reporting is needed for accurate assessment of dental implant complication frequencies and risk factors.

01:25Endocarditis II: Clinical Features of Infective Endocarditis
Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...
01:29Endocarditis IV: Nursing Management
Infective endocarditis (IE) is a chronic infection of the heart's endocardium, primarily affecting the heart valves. A detailed nursing assessment for a patient with IE involves collecting subjective and objective data to ensure an accurate diagnosis and timely intervention.Subjective DataThe nurse gathers information about the patient's symptoms and complaints during the subjective assessment. Patients with infective endocarditis often report non-specific symptoms that can mimic other...
01:25Peritoneal Dialysis II: Peritoneal Dialysis Systems and Complications
Peritoneal dialysis (PD) is a medical process that removes waste products and excess fluid from the body using the peritoneal membrane as a natural filter.Peritoneal Dialysis MethodsSeveral methods can be used for peritoneal dialysis, including Acute Intermittent Peritoneal Dialysis, Continuous Ambulatory Peritoneal Dialysis, and Automated Peritoneal Dialysis, also known as Continuous Cyclic Peritoneal Dialysis.Acute Intermittent Peritoneal Dialysis (AIPD) is used for patients with uremic...
01:24Chronic Kidney Disease II: Clinical Manifestations
Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...
01:24Healing II: Complications
Complications during healing arise when tissue repair is altered by local or systemic factors. These changes involve abnormal collagen deposition, altered biomechanics, and reduced vascular supply, impairing restoration of normal structure and function.Loss of FunctionScar tissue differs significantly from the original tissue it replaces. In the skin, fibrosis lacks adnexal structures such as hair follicles, sebaceous glands, and sweat glands. Their absence reduces tactile sensitivity, impairs...
01:22Complications of Diabetes Mellitus
Diabetes mellitus is a chronic metabolic disorder characterized by persistent hyperglycemia due to insulin deficiency, resistance, or both. Prolonged hyperglycemia disrupts metabolic homeostasis and leads to acute and chronic complications.Acute ComplicationsAcute complications result from sudden metabolic imbalance.Diabetic ketoacidosis (DKA) mainly appears in type 1 diabetes but may also develop in type 2 diabetes, particularly under extreme stress. It arises from severe insulin deficiency,...
