Outcome Measures

Primary Outcomes (2)

  • Pink and white esthetic scores (PES/WES)

    Baseline will be at the time of implant placement.Pink and white esthetic scores (PES/WES) will be recorded at 0.5, 1.5, 3.5, 5.5, 7.5, 10.5 years after implant placement.

    Up to 10 years after baseline

  • Radiographic bone volume

    Radiographic bone volume be assessed at pre-operation, 0 ,1.5, 1, 1.5, 3.5, 5.5, 7.5, 10.5 years after implant placement.

    Up to 10 years after baseline

Secondary Outcomes (9)

  • Implant survival

    Up to 10 years after baseline

  • Probing depth

    Up to 10 years after baseline

  • Modified plaque index

    Up to 10 years after baseline

  • Modified bleeding index

    Up to 10 years after baseline

  • Buccal marginal recession

    Up to 10 years after baseline

  • +4 more secondary outcomes

Study Arms (2)

Type 1 implant placement

ACTIVE COMPARATOR

Implant is placed immediately following tooth extraction in one surgical procedure

Procedure: Type 1 implant placement

Type 3 implant placement

ACTIVE COMPARATOR

Implant is placed in the site which is left to heal for 3 months following tooth extraction

Procedure: Type 3 implant placement

Interventions

Implant is placed immediately following tooth extraction in one surgical procedure

Also known as: Immediate implant placement
Type 1 implant placement

Implant is placed in the site which is left to heal for 3 months following tooth extraction

Also known as: Delayed implant placement
Type 3 implant placement

Eligibility Criteria

Age18 Years - 80 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • At least 18 years old and able to understand an informed consent
  • Adequate oral hygiene to allow for implant therapy consistent with standards of care.
  • Missing a single tooth in the maxillary anterior region
  • Presence of adjacent natural teeth

You may not qualify if:

  • Poor oral hygiene
  • Severe parafunctional habits, for example, bruxing and clenching
  • Presence of clinically active periodontal disease as expressed by probing pocket depths≄4 mm in combination with bleeding on probing.
  • Conditions that might lead to a possibly lowered regenerative capacity of the bone, for example, osteoporosis and Paget's disease
  • Pregnant or expecting to be pregnant
  • History of drug and alcohol abuse
  • History of systemic diseases that would contraindicate oral surgical treatment, for example, uncontrolled diabetes (defined as HBA1c level \>7%)
  • Radiotherapy in the head and neck area,
  • On certain medications like bisphosphonates or steroids currently or within the past three months
  • Absence of adjacent teeth
  • Unwillingness to return for the follow-up examination
  • Smokers (more than 20 cigarettes per day). Subjects smoking \<20 cigarettes per day were requested to stop smoking before and after surgery
