What is a characteristic of the microflora of a healthy implant site?
Predominantly gram-positive, aerobic, non-motile bacteria
What is a characteristic of the microflora of a peri-implantitis site?
Shift to gram-negative, anaerobic, and motile bacteria
What is a consequence of increased plaque accumulation around an implant?
Increased peri-implant probing depths
What is a similarity between peri-implantitis and periodontitis?
Similarity in microflora
What is the primary characteristic of peri-implantitis?
Inflammation in the peri-implant mucosa and subsequent progressive loss of supporting bone
What is the orientation of collagen fibers in the connective tissue adjacent to the implant collar?
Parallel to the implant surface
What is NOT a method for implant surface decontamination?
Probiotic therapy
According to Berglundh et al. (2018), what is a characteristic of peri-implantitis?
Increased probing depths and/or recession of the mucosal margin
What is a complication of peri-implantitis?
Progressive loss of supporting bone
What is NOT a characteristic of peri-implant health?
Radiographic bone loss
What is the main histological difference between healthy peri-implant and periodontal tissues?
The absence of cementum and periodontal ligament in peri-implant tissues
What is the orientation of collagen fibers around implants due to the lack of cementum?
Parallel to the implant surface
What is a characteristic of the sulcular epithelium in peri-implant tissues?
It continues apically with the junctional epithelium
What is a consequence of the lack of CT fiber insertion and decreased vascular supply in peri-implant tissues?
Greater susceptibility to bone loss
What is a key difference between the peri-implant and periodontal tissues in terms of vascularization?
The peri-implant tissues have fewer blood vessels in the mucosa than the periodontal tissues
What is the term for the disease that occurs due to plaque-induced inflammation in peri-implant tissues?
Peri-implantitis
What is the primary indicator of attachment loss around implants?
Changes in probing depths
What determines the probing depths around an implant?
Type and thickness of tissue surrounding the implant
What is the recommended frequency for follow-up radiographs if no complications are detected?
Every 2 years
Can peri-implant health exist around implants with reduced bone support?
Yes, peri-implant tissue health can exist around implants with reduced bone support
What is the significance of peri-implant bleeding on probing?
It is a sign of peri-implant inflammation
What is the purpose of radiographs at the time of implant placement, abutment insertion, and prosthesis insertion?
To establish a baseline for future comparisons
This quiz compares dental implants and natural teeth from a periodontal perspective, covering anatomy and disease maintenance. It discusses the differences between the two, including their composition and how they respond to disease. Ideal for dental students and professionals.
