What is the primary purpose of performing a free gingival graft (FGG) at an implant site before or during implant placement?
Answer: To increase the width of attached (keratinized) gingiva around the implant
A free gingival graft is harvested from the palate and placed at the implant site to increase the width of attached keratinized gingiva. Adequate keratinized tissue around implants is associated with better long-term tissue stability, easier maintenance, and reduced risk of peri-implant disease.
A connective tissue graft (CTG) around an implant restoration is most commonly used to achieve which outcome?
Answer: Augment soft tissue volume and improve the pinkesthetic contour
The subepithelial connective tissue graft adds bulk to the soft tissue, improving the tissue volume, contour, and color match to adjacent natural teeth — collectively referred to as 'pink esthetics.' This is especially important in the anterior zone where the gingival profile is visible when the patient smiles.
The term 'emergence profile' in implant dentistry refers to:
Answer: The contour of the restoration as it transitions from the implant or abutment through the gingival tissues to the visible crown
The emergence profile describes the three-dimensional shape of the restoration as it 'emerges' from the soft tissue, including the sub-gingival contours of the abutment and crown. A properly shaped emergence profile supports the peri-implant gingival tissues and creates a natural-looking transition from implant to crown.
Which technique uses a provisional implant crown to gradually shape the soft tissue before delivering the final restoration?
Answer: Progressive tissue conditioning using a provisional restoration
A provisional (temporary) crown is progressively modified — adding or removing material to change its subgingival contour — over several appointments to sculpt the peri-implant soft tissue into the desired shape and emergence profile before the final impression is taken for the permanent restoration.
What minimum width of keratinized mucosa around a dental implant is generally recommended to facilitate long-term tissue health and maintenance?
Answer: 2 mm
A minimum of 2 mm of keratinized mucosa around dental implants is widely recommended. Keratinized tissue is more resistant to mechanical trauma from toothbrushing and prosthetic components, and sites with less than 2 mm of keratinized mucosa are associated with greater plaque accumulation and higher rates of peri-implant disease.
In the anterior esthetic zone, which soft tissue landmark is most critical for achieving symmetry between an implant crown and the contralateral natural tooth?
Answer: The gingival zenith position and height
The gingival zenith — the most apical point of the gingival margin — and its height relative to the contralateral tooth is the primary landmark for anterior esthetic symmetry. Mismatched zenith positions or heights are immediately visible when a patient smiles and are a common reason for esthetic failure even when the crown itself looks good.
