Missing Teeth In Patients Research Articles

REHABILITATION OF AGENESIA 2.2 WITH PRAM INVOLVEMENT. CASE REPORT

Dental implants in dental agenesis are an effective and sustainable solution for replacing missing teeth in patients who have not developed some or more teeth permanently. Dental agenesis is a condition in which one or more teeth do not form or erupt normally. In the case of dental agenesis, dental implants can be used to replace missing teeth, giving the patient an aesthetic smile and the necessary functionality during chewing and speaking. Here are some important discussions about dental implants in the dental agency: Individual evaluation: Each patient with dental agenesis will be evaluated individually by the dentist. Issues such as the number and position of missing teeth, bone quality, and patient orofacial structure will be analyzed. The personalized treatment of each patient with dental agenesis has a unique situation, and the treatment of dental implants is personalized according to the needs and anatomy of the patient. Dental implants offer a predictable and sustainable treatment option. The stability of dental implants is anchored directly in the jaw or mandibular bone, providing stability and functionality similar to natural teeth. This allows patients to chew and speak without discomfort or restrictions. Aesthetic dental implants can be designed to match the teeth and shape of the patient's face, thus contributing to the nature of the aesthetics of the smile. They can be made with high quality materials and can be customized according to the color and shape of the patient's teeth. Preserving the bone structure of dental implants helps maintain the health of the jaw bones

Study of the radiofrequency-induced heating inside the human head with dental implants at 7 T.

Conductive dental implants are commonly used in restorative therapy to replace missing teeth in patients. Ensuring the radiofrequency (RF) safety of these patients is crucial when performing 7 T magnetic resonance scans of their heads. This study aimed to investigate RF-induced heating inside the human head with dental implants at 7 T. Dental implants and their attachments were fabricated and integrated into an anatomical head model, creating different measurement configurations (MCs). Numerical simulations were conducted using a 7 T transmit coil loaded with the anatomical head model, both with and without dental implants. The maximum temperatures inside the head for various MCs were computed using the maximum permissible input powers (MPIPs) obtained without dental implants and compared with published limits. Additionally, the MPIPs with dental implants were calculated for scenarios where the temperature limits were exceeded. The maximum temperatures observed inside the head ranged from 38.4°C to 39.6°C. The MPIPs in the presence of dental implants were 81.9%-97.3% of the MPIPs in the absence of dental implants for scenarios that exceeded the regulatory limit. RF-induced heating effect of the dental implants was not significant. The safe scanning condition in terms of RF exposure was achievable for patients with dental implants. For patients with conductive dental implants of unknown configuration, it is recommended to reduce the input power by 18.1% of MPIP without dental implants to ensure RF safety.

A prospective study of the performance of resin bonded bridgework in patients with hypodontia

Congenital absence of teeth presents a number of clinical challenges in young patients, and little is known about the success rate of restorative dental treatment in these patients. The aim of this study was to conduct a prospective clinical study of the performance of resin bonded bridges in patients with hypodontia. MethodsA prospective clinical observation study was undertaken in Cork Dental School and Hospital, Ireland. Forty patients (22 males, 18 females; age range 18–21 years) with a confirmed diagnosis of hypodontia rated as mild (n=26), moderate (n=8) or severe (n=6) participated. Following completion of the orthodontic phase of care, all patients had missing teeth restored with resin bonded bridgework (RBB) using a standardised protocol (48 FF; 17CL design). Patients were followed up for 24 months, with recall visits at 6, 12 and 24 months following provision of RBBs. Results65 RBBs were provided, 49 in the maxilla and 16 in the mandible; 43 bridges replaced anterior teeth and 22 replaced posterior teeth. After 24 months, 63 bridges were still in function and deemed to satisfy the preset criteria for success and survival. Two posterior bridges had failed due to repeated debond, and this was attributed to occlusal overload. 20% of the patients demonstrated some evidence of post orthodontic relapse, but this did not require further intervention. ConclusionIn the short to medium term, resin bonded bridgework provides a reliable and minimally invasive solution for replacing missing teeth in patients with hypodontia.
