Effects of health management of stomatology on the marginal bone resorption of minimally invasive implant in the elderly / 中华健康管理学杂志

ABSTRACT

Objective To evaluate the effects of health management of stomatology on the marginal bone resorption of minimally invasive implant in the elderly.Method Tottally 54 implants were placed in 37 elderly patients of missing teeth in maxillary molar areas and the patients were randomly divided into health management group and control group.Patients in the group of health management were guided to master the proper techniques of oral hygiene practices before and after the implantation and periodontal maintenance were carried out carefully until 1 year after loading of restoration.In the control group, oral hygiene was applied. X-ray and CBCT examinations were made and implant marginal alveolar bone loss (MBL) was measured 3, 6, 9, 12 months after loading with Planmeca PROMAX3D software. Besides, 3, 6, 9, 12 months after loading, improved plaque index (iPLI), modified bleeding index (mBI) and probing depth (PD) were also recorded. SPSS 15.0 was applied to analyze the data. Result Differences in diastolic and systolic blood pressure and changes in heart rate in patients during the intraoperative period were (8.86 ± 0.31) mmHg(1 mmHg=0.133 kPa), (19.18 ± 0.22) mmHg, (20.19 ± 1.84) times/min, which were significantly lower than those of the control group values [(16.55±1.08) mmHg, (28.31±2.30) mmHg, (20.19±1.84) times/min] (P<0.05 or 0.01);at 12 months after the load around the implant in oral health management group, the values of MBL and mSBI were 2.6 (2, 4), 2.1 (2, 4), which were significantly better than control group [4.3(3, 7), 4.3(3, 7)] (P<0.01);simultaneously, there was significant difference in the values of MBL and PD between experimental group (1.42 ± 0.03, 0.77 ± 0.24) and control group (1.59 ± 0.04, 0.54 ± 0.17) (P<0.01). Conclusion Well-performed health management of peri-implant could reduce the MBL and keep healthy soft tissue environment around implants.
