Peri-implant Papillary Height Comparison in Microsurgically and Macrosurgically Placed Dental Implants

Not Applicable

Completed

• Conditions: Dental Implants
• Interventions: Procedure: dental implant placement using magnifying loupes and microsurgical instruments; Procedure: macrosurgical dental implant placement

• Registration Number: NCT04189328
• Lead Sponsor: Krishnadevaraya College of Dental Sciences & Hospital

Brief Summary

This study compares the peri-implant soft tissue and crestal bone loss around single implants when placed macrosurgically and microsurgically.

Detailed Description

Black triangles in dentition especially in the anterior teeth would pose an esthetic concern. Interdental papilla height is crucial for eliminating this black triangle.

32 participants, 16 in two groups were assigned randomly. Microsurgical approach using microsurgical instruments and magnifying loupes were used for one group participants and similar procedure without magnifying loupes and microsurgical instruments was done in the other group.

comparsion of the microsurgical outcome is done by measuring peri implant papilla gain and radiographic crestal bone loss will be done between the groups.

Inclusion Criteria

• Patients desiring implant placement for replacement of missing tooth and willing to participate in the study

  • Non smokers
  • Patients who do not report any relevant medically comprimising conditions or had not received any radiation therapy in head and neck region for cancer therapy.
  • Subjects with satisfactory residual ridges who demonstrated adequate bucco-lingual and mesio-distal space for implant placement, that facilitates primary stability.

  • Implants to be placed in sites with previous periodontal disease
  • Bleeding disorder or on anticoagulant therapy
  • Systemic diseases that would negatively influence wound healing

Arm && Interventions

Group	Intervention	Description
test group	dental implant placement using magnifying loupes and microsurgical instruments	microsurgical implant placement
control group	macrosurgical dental implant placement	conventional macrosurgical implant placement

Primary Outcome Measures

Name	Time	Method
peri-implant papilla height	1 year	mesial and distal peri implant papilla height is measured in millimeter
jemt papilla index	1 year	papillary height gained around implant is scored using jemt papilla index 0 = no papilla and no indication of a curvature of the soft tissue adjacent to the implant crown are present; 1. = less than one-half of the papilla height is present, and a convex curvature of the soft tissue adjacent to the implant crown and adjacent tooth can be observed; 2. = at least one-half of the papilla height is present but not to the contact point between the teeth, the papilla is not completely harmonious with the adjacent papillae between the permanent teeth, and soft tissue is harmonious with adjacent teeth; 3. = the papilla fills the entire proximal space and is harmonious with the adjacent papillae, and soft-tissue contour is optimal; 4. = the papillae are hyperplastic and cover too much of the implant or the adjacent tooth, and the soft-tissue contour is irregular
marginal gingiva	1 year	buccal marginal gingival height is measured
pink esthetic score	1 year	scoring assigned to 7 soft tissue criteria by an examiner as 0,1,2,3 and the average of the total score is considered the final score. a maximum score of 14 can be alloted
crestal bone loss	1 year	radiographic crestal bone level around the implants measured from 1st thread of the implant to the coronal or apical most bone level in millimeters.

Secondary Outcome Measures

Name	Time	Method
gingival index	1 year	gingival index scores were recorded at each followup 0.1-1-mild gingivitis 1.1-2- moderate gingivitis 2.1-3 severe gingivitis
surgical time taken	1 day	the time taken right from the incision to the implant placement is watched and recorded.
visual analogue scale score	1 year	aesthetic score by the outcome investigator using VAS score sheet of 10 points. 1 being most painful and 10 being painless
probing depth	1 year	peri implant probing depth at each follow up was recorded
plaque index	1 year	plaque scores were recorded at each follow up 0.-0.9 good 1.0-1.9-fair 2-3-poor
