Comparison Criteria | Dental Bridge | Dental Implant |
Treatment technique | The two adjacent teeth are reduced to serve as abutments supporting the artificial tooth in between. | A titanium implant is placed directly into the jawbone to replace the missing tooth root. Once the implant integrates firmly with the bone, a dental crown is attached via an abutment. |
Preservation of natural teeth | Requires reduction of adjacent natural teeth, which may affect oral health if not carefully evaluated and performed with proper technique. | Does not affect neighboring natural teeth, helping preserve natural tooth structure and minimize invasion to healthy teeth. |
Durability after treatment | The lifespan typically ranges from 5 to 10 years, depending on the materials used as well as the patient’s daily oral hygiene habits. | The lifespan is long-term and can last from 20 to 30 years, or even a lifetime, provided that proper care and oral hygiene are maintained. |
Chewing function | It restores basic chewing function (approximately 60–70% compared to natural teeth); however, biting force and overall stability remain lower than those of natural teeth. | It restores chewing function almost equivalent to natural teeth (approximately 90–100%), providing stable biting force and a comfortable, natural eating experience. |
Aesthetics | The dental crown on a bridge provides good aesthetics initially; however, over time, darkened gum margins or exposure of artificial gingiva may occur. | It provides aesthetics that are very close to natural teeth, with minimal risk of exposed gum margins. In addition, a temporary crown can be placed immediately after implant placement, helping maintain tooth appearance and ensure aesthetics throughout the healing period before final restoration. |
Comfort during use | It may feel slightly bulky or uncomfortable during the initial period of use. | Firm and stable over the long term. |
Cost | Lower than dental implants. | Higher cost, requiring a more complex treatment process. |
Suitable candidates | Patients missing one or several teeth, excluding second molars. | Suitable for most cases of tooth loss, including a single missing tooth, multiple adjacent missing teeth, or complete edentulism. |
