Labial Bone Thickness Change in Immediate Implant Placement In Maxillary Esthetic Zone

Clinical and Radiographic Evaluation of Change in Labial Bone Thickness in Immediate Implant Placement In Maxillary Esthetic Zone Comparing a Jumping Gap of Less Than 2 mm to Equal or More Than 2 mm: A Non-randomized Clinical Trial

Guided Immediate Implant PlacementJumping GapLabial Bone Thickness ChangeBroken Down Tooth Rehabilitation

Summary

The goal of this clinical trial is to assess the effect of distance between the implant and the bone on the resultant bone thickness adjacent to the implant in place of a broken down tooth that happens to be bounded by two natural teeth. The main questions it aims to answer are: Does the horizontal implant position (and hence the gap between the implant and the socket wall i.e. jumping gap) affect the resultant labial bone thickness? Will it affect the quality of soft tissue, esthetics and patient satisfaction? Participants will have an implant placed using a surgical guide with a jumping gap either less than 2 mm or equal or more than 2 mm and will be asked to visit the clinic once every 3 months for checkups, radiographs, and readings.

Eligibility

Min Age: 21 Years

Inclusion Criteria5

  • Patients with a bounded single non-restorable upper tooth in the anterior maxilla (15-25) FDI (El Ebiary et al., 2023b)
  • Patients with an age range of 21 to 65 years old (Levine et al., 2022)
  • Patients with good oral hygiene with BoP ≤ 10 % (Chapple et al., 2018)
  • Compliant patients willing to follow up to one year.
  • Remaining labial bone thickness ≥ 1mm measured on C.B.C.T. and confirmed on the day of surgery after tooth extraction and before final implant placement.

Exclusion Criteria8

  • The presence of acute/active infection related to the non-restorable tooth (Block et al., 2009) cited in (Soegiantho et al., 2023)
  • Presence of labial bone defect as fenestration/dehiscence (Crespi et al., 2008) cited in (Soegiantho et al., 2023)
  • Large cyst or pathological lesion related to the tooth (Tallarico et al., 2016-2017) cited in (Soegiantho et al., 2023); (Morton, Wismeijer, Chen, Hamilton, Wittneben, Casentini, Gonzaga, Lazarin, Martin, Molinero-Mourelle, et al., 2023)
  • History of radiation to the maxilla (Cannizzaro et al., 2010) cited in (Soegiantho et al., 2023)
  • History of bisphosphonate therapy or other anti-resorptive agents (Cannizzaro et al., 2010) cited in (Soegiantho et al., 2023)
  • Uncontrolled systemic or metabolic disease. (Cecchinato et al., 2015) cited in (Soegiantho et al., 2023)
  • Patients with parafunctional habits or active periodontitis (Cannizzaro et al., 2010) cited in (Soegiantho et al., 2023) 8- Tobacco abuse (\>10 cigarettes per day) (Canullo et al., 2010) cited in (Soegiantho et al., 2023)
