This study aimed to estimate the impact of various customized healing abutments materials on the peri-implant soft tissue profile
A dental implant is a method for the replacement of lost teeth, with an excellent prospering percentage plus lasting functional rehabilitation without requiring any preparation of the nearby teeth. The usage of a healing abutment is one of the crucial clinical procedures that follows implant placement. It aids in establishing a stable and natural gingival emergence profile by supporting soft tissue shaping and shielding the implant platform. Various materials are available for healing abutments, which have an impact on biocompatibility, aesthetic results, soft tissue reaction, and patient comfort throughout the healing process. Polyether ether ether ketone (PEEK) healing abutments are offering a non-metallic, lightweight option with a modulus of elasticity similar to bone, but they have lower surface hardness compared to titanium and zirconia, and long-term data is still developing. 3D printed hybrid resin materials were introduced earlier, allowing faster and precise fabrication of permanent dental restorations. P-Crown V4 material is a newly introduced 3D-printed nanoceramic-filled resin reported to contain up to 70% nanoceramic filler to enhance strength and hardness.

Modified Plaque Index
The Modified Plaque Index was used to assess the degree of Plaque Accumulation. 0 No plaque 1. Plaque only detected with the probe 2. Plaque visible with naked eye 3. Abundant plaque
Time frame: Two months after healing abutment placement
Modified gingival index
The modified gingival index was used to assess the gingival condition. Each surface was evaluated and assigned a score from 0 to 4: 0 No bleeding 1. Isolated bleeding 2. Confluent bleeding 3. Profuse bleeding
Time frame: Two months after healing abutment placement
Papilla index (Jemt Index)
The papilla index (Jemt Index) was used to assess the Papilla condition. 0 No papilla present; no soft tissue curvature; empty space present. 1. Less than half of the papilla height is present 2. At least half of the papilla height is present, but it does not completely fill the space. 3. The papilla fills the entire embrasure space and fills the gap completely (optimal). 4. The papilla is hyperplastic covering too much of the tooth/implant.
Time frame: Two months after healing abutment placement
