1. Preserves Jaw Bone- A common thing to see after tooth extraction is residual ridge resorption, this causes the jaw bone to reduce in height and width. Implant stimulates the tooth in same way as the natural tooth, hence preserving the jaw bone in natural form.
2.Better function- Implant is the closest replica of natural tooth, It's function is best in all kind of dental prosthesis.how ever the placement and design does matter for it's best function.
3.Best Aesthetics and cosmetic results- No other dental prosthesis can produce aesthetic which is equal to the implants, It provides a look of emergence ( as if tooth is coming out of the gums)
4. Best stability and retention- Due to osteointegration of implant into the bone it is best in retention and stability . No other dental prosthesis can be compared with this.
5.Comfort- no flanges, no retentive clasps, no preparation of adjacent tooth, it's the most comfortable type of dental prosthesis.

Disadvantages
1.Expensive- Due to the technical sensitivity and use of high end equipment and materials implant is a costly option.This is best prosthetic treatment but patient can afford it or not this is the concern.
2.Limitations due to Medical conditions -Medically compromised patient can't have implants, even if they want to go for implants it's not possible to provide the implant surgery.
3.Patient compliance- Implant treatment need patience and time by patients as well as dentist, lot's of recalls and after care visits require good patient compliance.
4. Limitation due to anatomical factors- It can't be placed on very part of the jaw, It have some anatomical limitations.
