Long-term survival rates of tapered self-tapping bone-level implants after immediate placement: a positional effective rationale

BACKGROUND

Immediate implant placement has gained popularity due to its several advantages. However, immediate placement has its challenges, including concerns about primary stability and bone formation around the implant. The aim of the present study is to evaluate the clinical outcomes of tapered, sand-blasted, and acid-etched internal submerged dental implants in various regions of the jaw bones and to provide a positional rationale for immediate implant placement.

METHODS

Between 2009 and 2018, a single surgeon at Seoul National University Dental Hospital in Seoul, Korea, immediately inserted 49 dental implants with tapered bone-level design after extraction, in a total of 34 patients. The clinical outcomes were collected and evaluated, focusing on location of implant placement and marginal bone loss (MBL), with consideration of other parameters such as implant diameter and length.

RESULTS

Of 49 immediately installed Luna® (Shinhung Co., Seoul, Korea) dental implants, 23 were placed in the mandible, and 26 were set in the maxilla. The mean age of patients at the time of installation was 65.91 years, ranging from 40 to 86 years. The average follow-up period was 7.43 years, with a range of 5 to 14 years. After a 5-year retrospective evaluation of tapered, sand-blasted, and acid-etched internal submerged dental implants for immediate implant placement, the cumulative survival rate was 93.88%, with 100% survival rate in the mandible and premolar region of both the maxilla and mandible.

CONCLUSIONS

After a 5-year evaluation, tapered, sand-blasted, and acid-etched internal submerged dental implants demonstrated good efficacy for immediate placement in various locations within the dental arches, exhibiting effective clinical performance.

706 IMPROVING PRESCRIPTION OF PARKINSON’S DISEASE MEDICATIONS FOR PATIENTS ON ELDERLY CARE WARDS AT ROYAL STOKE UNIVERSITY HOSPITAL

Introduction

Patients with Parkinson’s disease (PD) are commonly admitted into hospital with various acute medical conditions. Inaccurate prescription can result in adverse effects, increased hospital stay, and increased morbidity and mortality. We present a QIP conducted to improve PD medication prescription pattern among doctors and medication delivery from the nursing staff.

Method

In PDSA 1, we conducted a survey among doctors and nurses to assess their initial knowledge on PD medications. A baseline review of PD prescriptions on our Frail Elderly Assessment Unit (FEAU) was conducted. Our interventions include Introduction: of PD medication alert sticker attached to drug charts and recorded drug chart when they are taken off the wards. In PDSA 2, repeat survey was carried on Elderly care wards. We also reviewed PD prescriptions over a 2-week period on Elderly care wards.

Results

During the surveys, there were 55 respondents in PDSA 1 and 51 respondents in PDSA 2. The percentage of those who feel PD medications are critical medications remain similar in both cycles (98%). There was an improvement in the awareness of PD stickers from 44% to 83%. Those who feel PD alert stickers are appropriate improved from 93% to 100%. Respondents who chose all included appropriate PD medication sources for improving prescription pattern improved from 38% to 62%. There were 8 prescriptions during PDSA 1 and 21 prescriptions during PDSA 2. The use of PD stickers improved from 0% to 76%. The numbers of PD medications prescribed appropriately improved from 50% to 65%.

Conclusion

An improvement in prescription pattern was demonstrated, as we hope to improve patient safety and increase awareness across the trust. Our recommendations include use of PD medication alert sticker and recorded drug chart. We discussed our plans in Medicine Governance meeting, departmental newsletter, and presented in departmental audit meeting.
