Brief Summary
The objectives of this study are to analyze the oral microbiome modulations occurring during the transition from partial (with some residual teeth) to full edentulous (without remaining teeth) status and implant placement in subjects affected by severe periodontitis; to evaluate if microbiome changes in relation to the used of different implant material/surface; and to assess the variance of the changes to determine the sample size for future longitudinal prospective studies.

Outcome Measures
Primary Outcomes (2)
Oral microbiome composition changes in patients who are dentate, edentulous, and have dental implants
To analyze the oral microbiome modulations through DNA analysis of microbial samples occurring during the transition from partial (with some residual teeth) to full edentulous (without remaining teeth) status and implant placement in subjects affected by severe periodontitis
Through study completion, an average of 24 months
Oral microbiome changes in two different implant platform types
To evaluate if microbiome changes through DNA analysis of microbial samples in relation to the use of different implant material/surface
Through study completion, an average of 24 months
Secondary Outcomes (1)
Sample size
Through study completion, an average of 24 months
Study Arms (2)
Intra-Lock Fusion Implants
These patients will receive Intra-Lock Fusion Implants during implant placement
Tapered Pro Implants
These patients will receive Tapered Pro Implants during implant placement
Interventions
Pool microbial sampling will be performed and changes in the microbiome will be evaluated and compared for differences
Eligibility Criteria
The study population will consist of patients with stage III or IV periodontitis who are patients at the Case Western Reserve University School of Dental Medicine in the Department of periodontitis who are seeking to remove all of their remaining teeth and replace the teeth lose to periodontal disease with dental implants
You may qualify if:
- At least 21 years of age
- Diagnosis of Stage III or IV periodontitis based on full mouth probing and full mouth x-rays
- Planned for full mouth extraction and replacement by dental implants.
- Rehabilitation with Implant supported restorations either maxilla and/ or mandible.
- At least 2 implants available for examination.
- No bone augmentation required.
You may not qualify if:
- Conditions requiring chronic routine prophylactic use of antibiotics.
- Conditions requiring prolonged use of steroids.
- History of leukocyte dysfunction and deficiencies
- Bleeding disorders
- History of neoplastic disease requiring use of radiation or chemotherapy
- Metabolic bone disorders
- Uncontrolled endocrine disorder
- Use of any investigational drug or device within the 30 day period prior to implant surgery.
- \. Alcoholism or drug abuse 11. Patient infected with HIV 12. Condition or circumstances, in the opinion of the investigator, which would prevent completion of study participation or interfere with analysis of study results, such as history of non-compliance, unreliability.
- Local inflammation
- Mucosal disease such as erosive lichen planus
- History of local irradiation therapy
- Osseous lesion.
- Active infection with suppuration or fistula track.
- Persistent intraoral infection different than periodontitis

Biospecimen
Separate pooled samples will be collected from 3 areas of the mouth: oral mucosa, tongue, Peri-implant sulci (when applicable). Surfaces will be swabbed for 30 seconds each with a single CatchAll™ Swab. Care will be taken to avoid contacting the teeth. The swab will be immediately swirled in 400 uL Tris-EDTA buffer, pressing the swab against the tube walls for 20 seconds to transfer the material to the solution. The swab will be then discarded. The procedure will be repeated, but this time swabs will be placed in 400 uL of RNA Cell Protect (Qiagen). Subgingival plaque collection: The subgingival plaque will be then sampled with a Gracey curette obtaining samples from all available surfaces, and placed in 400 uL of TE buffer or 400 uL RNA Cell Protect (Qiagen). Samples will be immediately transferred to a -80 degree C freezer until further processed.
