简要总结

The purpose of the study is to evaluate if using Erbium-doped yttrium aluminium garnet laser, Erbium YAG laser (Er:YAG) laser could have adjunctive benefits to the conventional standard mechanical debridement to ablate the infected tissue around the dental implant and detoxify the contaminated implant surface for resolving peri-implant infection and enhance bone regeneration of peri-implant defects.

详细描述

The purpose of the study is to evaluate if using Er:YAG laser could have adjunctive benefits to the conventional standard mechanical debridement to ablate the infected tissue around the dental implant and detoxify the contaminated implant surface for resolving peri-implant infection and enhance bone regeneration of peri-implant defects.

This study involves one center and a double-blinded randomized controlled clinical trial is planned. Twenty-four adult patients in the need of surgical treatment due to peri-implantitis will be included. Six visits are needed for each patient including a 24 week follow-up visit.

Specific Aim 1: To compare the clinical benefit of Er:YAG laser-assisted peri-implant defect debridement and surface detoxification with conventional mechanical debridement for regenerative therapy

Specific Aim 2: To evaluate whether Er:YAG laser-assisted regenerative surgical therapy can decrease bacterial load and alter microbial profile

Specific Aim 3: To analyze whether Er:YAG laser-assisted regenerative surgical therapy can impact the molecular profile of the peri-implant crevicular fluid (PICF) and the stability of the treatment

入选标准

  • Subjects, aged 18 - 85 years
  • Physical status according to the American Society of Anesthesiologists (ASA) I or II, which includes patients who are systemically healthy or suffer under mild to moderate, but well controlled systemic diseases.
  • Subjects having a minimum of 1 dental implant with peri-implantitis.
  • Dental implants with peri-implantitis ≥ 2 threads exposed (infrabony defect) identified on the radiograph and pocket probing depth (PPD) ≥ 5mm, with bleeding on probing (BOP) and/or suppuration (pus)
  • The implants are in function for at least 6 months
  • Only rough surface implant will be included in this study

排除标准

  • Long-term use of antibiotics > 2 weeks in the past two months
  • Obvious malpositioning of the dental implants
  • Subjects taking medications known to modify bone metabolism (such as bisphosphonates, corticosteroids, Hormone replacement therapy for menopausal women, parathyroid hormone, Denosumab, strontium ranelate)
  • Pregnant females or those planning to become pregnant
  • Subjects with a history of major diseases, oral cancer, sepsis or those having adverse outcomes to oral procedures in the past, will be excluded
  • Mobility of dental implants
  • History of alcoholism or drug abuse
  • Current smokers
  • Diseases of the immune system or any medical condition that may influence the outcome (uncontrolled diabetes (HbA1c >8)
  • Uncontrolled systemic disease or condition known to alter bone metabolism, like Osteoporosis, Osteopenia, Hyperparathyroidism, Paget's disease
  • Premature Exclusion Criteria:
  • The researcher believes that it is not the best interest of the subject to stay in the study
  • If the subject becomes ineligible to participate based on the exclusion criteria
  • If the subject's medical condition requires interventions which preclude involvement in the study (radiation therapy, chemotherapy, etc)
  • If the subject does not follow study related instructions
  • The study is suspended or canceled.

结局指标

主要结局

Change in Periodontal Probing Depths (PD)

时间窗: Baseline and 24 Week

PD will be measured in millimeters. Change in PD measurements were calculated between baseline and 24 weeks.

Change in Clinical Attachment Level (CAL)

时间窗: Baseline and 24 Week

CAL will be measured in millimeters. Change in subject CAL measurements were calculated between baseline and 24 weeks.

Change in Bleeding on Probing (BOP)

时间窗: Baseline and 24 Week

BOP will be measured dichotomously as 0 or 1. Score 0=no bleeding present Score 1=bleeding present Change in subject BOP score was calculated between baseline and 24 weeks and reported as percent of sites with BOP.

Change in Radiographic Bone Fill (RBF)

时间窗: Baseline and 24 Week

Peri-implant bony defect change will be measured compared to baseline. Participants' standardized radiographs were used to determine bone level changes between baseline and 24 weeks.
