Bisphosphonates are a class of drugs that prevent the loss of bone density, making them a primary therapeutic regimen for conditions characterized by excessive bone resorption. Primary hyperparathyroidism involves excessive parathyroid hormone (PTH) production, which can lead to bone loss, but bisphosphonates are typically used as an adjunct or in specific cases, not as the primary indication. Age-related (postmenopausal) osteoporosis is the most common indication for bisphosphonate therapy. The drop in estrogen levels after menopause accelerates bone turnover and bone loss, and bisphosphonates effectively slow this process. Rickets is a childhood condition caused by a lack of vitamin D, calcium, or phosphate, leading to softened and weakened bones. Treatment focuses on addressing the nutritional deficiency, not using bisphosphonates. Chronic kidney disease (CKD) can lead to various bone and mineral disorders, but bisphosphonate use requires careful consideration due to potential accumulation and side effects in patients with reduced kidney function.

Solution The following are the effects when Herbst appliance used for treatment of Class II malocclusion:
1. Class I molar relation or over-corrected Class I molar relation.
2. Increased mandibular growth
3. Distal driving of maxillary molars which helps to achieve molar relation.
4. Reduction of overjet by increasing mandibular length and proclination of mandibular incisors.
5. Inhibitory effect on sagittal maxillary growth
6. Weislander suggested double contour of glenoid fossa which indicates anterior transformation of glenoid fossa
7. Increased SNB angle and decreased SNA angle.
