Changes in soft tissues around immediate full-arch rehabilitations: a prospective study

Area of Science:

• Dental Implantology
• Periodontology
• Prosthodontics

Background:

• Aesthetic appearance is increasingly important in dentistry.
• Maintaining soft tissue quality around dental implants is crucial for long-term success.
• Immediate implant placement and provisionalization can enhance peri-implant tissue control.

Purpose of the Study:

• To evaluate soft tissue changes around immediately loaded dental implants in full-arch rehabilitations.
• To assess the stability of the soft tissue-implant interface over a 3-month period.

Main Methods:

• Prospective study of 15 subjects undergoing immediate full-arch rehabilitations.
• Provisional restorations made of bisphenol-A-glycidyldimethacrylate (BIS-GMA) and resin were used.
• Soft tissue and papilla levels were measured using a periodontal probe relative to crown margins.

Main Results:

• No significant changes in mid-facial soft tissue levels were observed over 3 months.
• Mesial and distal papilla levels showed minimal average changes (-0.035 mm and -0.05 mm, respectively).
• A reduction in the plaque score index was noted during the follow-up period.

Conclusions:

• Immediate loading of full-arch dental implants may maintain mid-facial soft tissue levels.
• The absence of significant papilla loss, contrary to some literature, suggests favorable outcomes.
• Further research is needed to elucidate the mechanisms behind soft tissue maintenance in these cases.
