Screw-retained implants offer many benefits to patients. One of the main advantages is ease of maintenance. Dentists can remove the crown without damaging it, which is helpful for cleaning or when the crown becomes loose.
They also provide long-term durability. According to a clinical study, screw-retained implants have a survival rate of 94.6% and a success rate of 89.7% over approximately 13 years.
Another major advantage is the reduced risk of gum inflammation. Unlike cement-retained implants, these do not use dental cement, which may otherwise irritate the gums. This makes screw-retained implants safer for patients with gum sensitivity.
They also offer placement flexibility. Dentists can angle them in tight spaces, making them suitable for more complex clinical cases.
Cement-retained dental implants offer a number of aesthetic and practical benefits. One key advantage is their natural appearance. Without visible screw holes, these implants blend in seamlessly with surrounding teeth — particularly important for front tooth restorations. A study reports high satisfaction rates in aesthetics among patients receiving cement-retained implants.
They also provide a strong, secure fit. The crown remains firmly in place during chewing or biting. In one clinical study, 87.5% of patients expressed high satisfaction, and their surrounding gums remained healthy over time.
These implants are flexible in challenging placements. When implant angles are suboptimal, cement-retained crowns offer better adaptability. Long-term data supports their durability, with survival rates reaching 96.4%, making them comparable to screw-retained implants. (Source)
| Study | Implant Type | Looks After 6 Months | Looks After 12 Months | Big Difference? |
|---|---|---|---|---|
| Chokaree et al. | Special Healing Abutment | Better (p = 0.022) | N/A | Yes |
| Perez et al. | Regular Healing Abutment | N/A | No big difference | No |
| Implant Type | Easy to Fix or Clean? |
|---|---|
| Screw-retained | Yes, crown comes off easily |
| Cement-retained | No, crown may need cutting |
Both implant types work well for a long time. Studies show they have high success rates and few problems, about 3–5%. Over five years, bone changes around the implants were small. Cement-retained implants showed a change of -0.23 mm, while screw-retained implants had -0.15 mm. Both are reliable choices for lasting use. (Source: PMC Journal - Long-Term Implant Performance)
