Abstract

Ultrasound Transmission Velocity measurement on female patients with treated periodontal diseases and implants R. Mengel, P. Hadji, P. Kann, B. Lechner The aim of the clinical study on female patients with treated periodontal diseases and implants was the determination of the bone mineral density from mandibula and maxilla using a Ultrasound Transmission Velocity (UTV, DBM Sonic 1200, Italy) measurement. 20 edentulous patients with GAP and GCP (average age: 55,5 years, all non-smokers) got 74 implants (MK II, Nobel Biocare, Zürich, Swiss and Osseotite 3i, West Palm Beach, FL, USA) inserted. After integration of the implants’ superstructures the patients have been controlled in a 3-month-recall over a period of 2 to 5 years. In each session the clinical parameters on teeth and implants were recorded. Radiological check-ups with dental X-rays were made before implantation, after integration of the superstructures and 1, 3 and 5 years later. The determination of the bone mineral density was measured by UTV 3 years after integration of the superstructures and controlled by computerized X-ray densitometry, too. The clinical examination showed a loss of attachment of 0.15mm (teeth) and 0.41mm (implants) per year. The bone loss averaged out at 0.21 % (teeth) and at 0.15mm (implants) per year. UTV diagnostics gave hints of osteoporosis (1435 m/s) by two patients and of osteopenia (1516 m/s) by 4 women. The analogical Dual X-ray (DXA) values were T-scores ≤ -2.5 for osteporosis and T-scores -1.5 to -2.5 for osteopenia. The patients with osteoporosis or osteopenia showed no difference concerning clinical and radiological results on teeth and and implants in comparison to healthy patients. The UTV scores were compared to DXA-data statistically and showed good correlation. The intraoral measurement of Ultrasound Transmission Velocity seems to be a non invasive, sufficient alternative for bone density measurements of the alveolar ridge due to the high correspondency between the UTV and DXA data.
