To find a cost-effective dental hospital in Beijing for dental implant surgery, the following factors can be considered:

1. Hospital qualification : Select hospitals with formal medical qualifications to ensure medical safety and service quality.
2. Doctor experience : Understand the professional background of the doctor and the clinical experience of implant teeth, and select an experienced doctor for surgery.
3. Price transparency : Choose hospitals with transparent prices to avoid invisible consumption.
4. Patient evaluation : Refer to the evaluation and feedback of other patients to understand the service quality and treatment effect of the hospital.

In Beijing, there are several well-known dental hospitals that provide dental implant services, such as Beijing Dental Hospital, Peking University Dental Hospital, etc. These hospitals usually have advanced equipment and professional doctors, but the price may be relatively high. If the budget is limited, consider some private dental clinics, which may offer more competitive prices.

It is recommended to consult and compare with several hospitals before selecting hospitals to understand their dental implant schemes, cost details and possible preferential activities. At the same time, you can also use network platforms such as health consulting websites and social media to view the evaluations and recommendations of different hospitals.

Please note that although price is an important consideration, medical quality and safety should be paid more attention when choosing dental implant hospitals to avoid sacrificing treatment effect and health safety due to the pursuit of low prices.
